New Class Additions Updated!

Shamans

In World of Warcraft: Cataclysm, we'll be making lots of changes and additions to class talents and abilities across the board. In this preview, you'll get an early look at some of the changes in store for the shaman class, including a rundown of some of the new spells, abilities, and talents, and an overview of how the new Mastery system will work with the different talent specs.

New Shaman Spells

Primal Strike (available at level 3): Primal Strike is a new weapon-based attack that every shaman will learn very early in the game. Our goal with this ability is to make leveling as Enhancement rather than as Elemental more viable, since many key Enhancement talents become available at fairly high levels.

Healing Wave (level 4): While the shaman already has an ability called Healing Wave, we're adding another spell to the class's direct-healing arsenal and giving it a familiar name. The current Healing Wave will be renamed Greater Healing Wave, and the intent is for the 'new" Healing Wave to be the shaman's go-to heal. Lesser Healing Wave and Greater Healing Wave will be used on a more situational basis.

Unleash Weapon (level 81): Unleashes the power of your weapon enchants for additional effects (see below). A dual-wielding Enhancement shaman will activate the effects of both of their weapon enchants. Instant cast. 30-yard range. 15-second cooldown. Undispellable.

Here are a few examples of effects we're considering for this ability:

Windfury Weapon – Hurls a spectral version of your weapon at a target, dealing 50% weapon damage and increasing the shaman's Haste for the next five swings.
Flametongue Weapon – Deals instant Fire damage and buffs the shaman's next Fire attack by 20%.
Earthliving Weapon – Heals the target slightly and buffs the shaman's next healing spell by 20%.

Healing Rain (level 83): An area-effect heal-over-time (HoT) spell that calls down rain in a selected area, healing all players within it. There is no limit to the number of players who can potentially be affected; however, there are diminishing returns when healing a large number of targets, much like the diminishing returns associated with AoE damage spells. This should give Restoration shaman another healing tool that improves their group-healing and heal-over-time capabilities. 2-second cast time. 30-yard range. 10-second duration. 10-second cooldown.

Spiritwalker's Grace (level 85): When this self-targeted buff is active, your spells are no longer interrupted by movement and possibly even by your own attacks. This will give shaman of all three specs another way to heal or do damage when it’s necessary to move in both PvE and PvP. Instant cast. 10-second duration. 2-minute cooldown.

Changes to Abilities and Mechanics

In addition to adding new spells, we're planning to make changes to some of the other abilities and mechanics you're familiar with. This list and the summary of talent changes below it are by no means comprehensive, but they should give you a good sense of what we intend for each spec.

Restoration shaman and other healing classes will need to pay attention to mana more than they've had to during Wrath of the Lich King. Spirit will be the Restoration shaman's primary mana-regeneration stat.
We're making changes to which classes and specs are able to dispel magic, diseases, curses, and poison, largely for PvP purposes. Shaman will have Cleanse Spirit as a baseline ability, but it will only remove curses. Restoration shaman will have a talent that will improve Cleanse Spirit so that it also removes magic. Shaman will no longer be able to remove poison.
Cleansing Totem will be removed from the game, as we want dispels to be a decision for players, not something done mindlessly. To that end, all dispels will cost slightly more mana, and you will waste the spell if you cast it when there is nothing to remove. (Currently, the dispel is only cast when there is something to remove, which encourages spamming 'just in case.") We will balance PvE dispelling with this new model in mind.
Totem of Wrath now will replace Flametongue Totem for all shaman, and dropping this totem will buff the group's spell power by 4%. Elemental shaman will have a talent that lets all Fire totems provide +10% spell power, allowing them to drop Searing, Magma, or Fire Elemental Totems without losing their spell-damage buff. The 4% and 10% buffs will be exclusive with each other and with the warlock's Demonic Pact, so you can't benefit from all of them at once. We're also considering letting Elemental drop Searing Totem at range.
We want to free up Enhancement global cooldowns to make the spec more dynamic to play. We're considering, for example, increasing the cooldown of Lava Lash so shaman have time to work other interesting abilities into their rotation.


New Talents and Talent Changes

Elemental Reach will be simplified so shaman have a more consistent spell range.
We plan to add Earthquake as a deep Elemental talent for targeted and persistent AoE.
Spirit Link will likely be worked back into deep Restoration in some form. The idea is that you will be able to link targets together so they share damage. When we had previously tried to implement Spirit Link, it was hard to balance and a little confusing. However, we really liked the concept -- and so did players -- so we are trying to bring it back.
Elemental will have a deep talent that allows Spirit (which will appear on the gear they share with Restoration shaman) to boost their Hit rating.
Ancestral Knowledge will boost mana pool size, not Intellect.
Enhancing Totems will be replaced with Focused Strikes, which will improve the damage of the new spell Primal Strike and Stormstrike.
With the Mastery system, we're also considering removing a number of talents that grant passive bonuses, such as Mental Quickness, Improved Windfury Totem, Mental Dexterity, Call of Thunder, Tidal Mastery, Purification, Nature's Blessing, and others, to allow players more freedom to choose more interesting talents.


Mastery Passive Talent Tree Bonuses

Elemental
Spell damage
Spell Crit
Elemental Overload

Elemental Overload: Your direct-damage spells have a chance to proc a less powerful 'bonus" version of the spell. This will work much like the current Lightning Overload talent, but would also apply to Lava Burst.

Enhancement
Melee damage
Melee Haste
Nature Damage

Nature Damage: This will provide a passive bonus to the Nature damage dealt by the Enhancement shaman.

Restoration
Healing
Meditation
Deep Healing

Deep Healing: Your direct heals will do more healing when the target's health is lower. This will scale to damage (e.g. someone at 29% health would receive more healing than someone at 30%) rather than have arbitrary break points.

We hope you enjoyed this preview, and we're looking forward to hearing your thoughts and feedback on these additions and changes. Please keep in mind that this information represents a work in progress and is subject to change as development on Cataclysm continues.

Update
Just to clarify a few things:

Meditation – the amount of mana you regenerate in combat as a function of your Spirit.

Also of note, you only get one set of passive talent tree bonuses: the tree in which you’ve spent the most points. Sub-speccing in another tree will not net you those bonuses in addition.

Last but not least, it's the intention of Primal Strike to let shaman play as an Enhancement at low levels. Currently when leveling in this spec, you end up just using Lightning Bolt a lot so you feel like an Elemental shaman instead. At a higher level, Primal Strike gets replaced by Storm Strike. They share a cooldown so Enhancement just won’t ever use Primal Strike after that, in the same way that Prot warriors don’t use Sunder Armor once they have Devastate or Feral druids don’t use Claw once they get Mangle.

Warlock


In World of Warcraft: Cataclysm, warlocks will receive changes to their class talents and abilities. Outlined below are some of these changes. Keep in mind that this is an early preview and that these modifications are still under development, so you may see further adjustments to the listed changes as we get closer to launch. That said, here is a first look at these new warlock spells and abilities!

New Warlock Spells

Fel Flame (level 81): Quick-hitting spell dealing Shadowfire damage. This is similar to the mage ability Frostfire Bolt, in that the lower of the two resistances (in this case shadow and fire) on your target will be used for calculating its damage. Additionally, Fel Flame refreshes the duration of Immolate and Unstable Affliction. Our goal for Fel Flame is to provide a spell that's good for mobility and for use by Destruction and Demonology specs. Also, did we mention it uses green fire? Yep. Instant cast.

Dark Intent (level 83): Increases the target's chance for a critical effect with periodic damage or healing spells by 3%. When the target lands a crit, you get a buff to your damage for 10 seconds. This effect stacks up to three times.

Demon Soul (level 85): Fuses the warlock's soul with his or her demon. This provides warlocks with a self-burst cooldown to use. The specific effects granted by Demon Soul depend on the demon chosen. Demon Soul lasts for a certain number of charges or until it expires (around 20 seconds), depending on the demon used. 2-minute cooldown.

Soul Shard Overhaul

This major change regarding Soul Shards was previously announced at BlizzCon 2009. Soul Shards will no longer be inventory items, but instead a new UI resource mechanic. Warlocks will have 3 Soul Shards that can be used during a fight and will not be able to gain additional shards during combat. Soul Shards will not be required outside of combat. Soul Burn will consume a Soul Shard resource, thereby allowing you to use the secondary effects of some spells. Soul Burn has no mana or health costs and is off the global cooldown. Planned secondary effects are outlined here.

Summon Demon + Soul Burn = summon the demon instantly.
Drain Life + Soul Burn = Reduces cast speed by 60%.
Demonic Circle + Soul Burn = Increases movement speed by 50% for 8 seconds after teleporting.
Unstable Affliction + Soul Burn = Instantly deals damage equal to 30% of its effect.
Soul Fire + Soul Burn = Instant cast.
Healthstone + Soul Burn = Increases total health by 20% for 8 seconds.
Searing Pain + Soul Burn = Increases the crit chance of Searing Pain by 100%, and subsequent Searing Pain spells by 50% for 6 seconds.

Next you will find a list of some of the warlock spell and talent changes for the release of Cataclysm. There will be further changes, but those revealed below should offer some insight into our goals.

Changes to Abilities and Mechanics

All warlock damage-over-time (DoT) spells will benefit from crit and haste innately. Haste will no longer act to reduce the DoT's duration, but rather to add additional ticks. When reapplying a DoT, you can no longer "clip" the final tick. Instead, this will just add duration to the spell, similar to how Everlasting Affliction currently works.
Curse of Agony and Curse of Doom will be converted into Bane of Agony and Bane of Doom. Bane spells are considered magic instead of curses. This means you will be able to cast one Bane (e.g. Bane of Agony) and one Curse (e.g. Curse of Elements) on a single target.
Hellfire will no longer deal damage to the warlock.
Imps will lose Fire Shield, but will gain a new ability, Burning Ember, which is a stacking DoT.
The succubus melee range will be increased. The succubus will no longer have Soothing Kiss, but will instead have Whiplash, which knocks back all enemies within 8 yards.
Voidwalker Torment will do increased damage and generate a lot of area-of-effect (AoE) threat. Suffering will become a single-target taunt.


New Talents and Talent Changes

Pandemic will now cause Drain Soul to refresh Unstable Affliction and Bane of Agony on targets below 25% health.
The ability Fel Domination will be removed (because Soul Burn accomplishes the same effect).
Demonology will gain a new direct-damage spell, Demon Bolt. Demon Bolt will add a debuff that improves the damage done by the demon to the target.
We plan to add a new talent, Impending Doom, which will give certain spells a chance to reduce the cooldown on Metamorphosis and Bane of Doom.
Metamorphosis will no longer be subject to demonic crowd control. Furthermore, abilities available only while under the effects of Metamorphosis will be altered to put more emphasis on the warlock's own spells.
Shadowburn will now do additional damage to targets below 25% health.

Mastery Passive Talent Tree Bonuses

Affliction
Spell Damage
Spell Crit
Shadow DoTs

Shadow DoTs: The damage caused by Shadow damage-over-time spells is increased.

Demonology
Spell Damage
Spell Haste
Demon Damage

Demon Damage: The damage caused by pets and Metamorphosis is increased.

Destruction
Spell Damage
Spell Critical Damage
Fire Direct Damage

Fire Direct Damage: The damage caused by Fire direct damage spells is increased.

Well that concludes this Cataclysm preview for the warlock class. The development of these changes will continue to evolve in the coming months. Please be sure to provide any feedback and thoughts you might have on what was covered here.

[...]

Here are a few points of clarification on some of the popular questions or concerns we're seeing.

On regenerating shards in combat, we will add a mechanic to regen shards if we find that we need to in order to handle variable combat length. We haven’t added one yet because we really want to emphasize locks using shards at the right time and not as fast as they can with then an Evocation-like spell to bring them back again. These are supposed to be special moments in a fight -- think Bloodlust perhaps -- and not used every 20 seconds on cooldown (or whatever the cooldown ends up being).
Demon lovers, we haven’t ruled out adding a new demon, but we want to be very careful here. We’ve had a hard enough time finding niches for some of the current ones. So we first want to make sure existing demons are cool before we’re faced with Q&A several months from now asking why the new demon either isn’t cool enough, or why warlocks no longer use, say, their felhunter because of the new demon.
The intent for Hellfire is for it to be a specialty of Demonology warlocks. Affliction would use Seed of Corruption and Destruction would use Rain of Fire.

Priest

In World of Warcraft: Cataclysm, we'll be making lots of changes and additions to class talents and abilities across the board. In this preview, you'll get an early look at some of the changes in store for the priest class, including a rundown of some of the new spells, abilities, and talents, as well as an overview of how the new Mastery system will work with the different talent specs.

New Priest Spells

Heal (available at level 16): While priests already have a spell called Heal, the existing version becomes obsolete at higher levels, which is something we intend to change in Cataclysm. Introduced at a low level, the "new" Heal spell will functionally work much like a down-ranked Greater Heal did in the past, adding more granularity to your direct-healing arsenal. If you need to heal someone a moderate amount and efficiency is an issue (making Flash Heal the incorrect spell for the job), then Heal is what you want to use. Heal is intended to be the priest's go-to direct-healing spell unless they need something bigger (Greater Heal) or faster (Flash Heal). We will be following a similar philosophy with all the healing classes.

Mind Spike (level 81): Deals Shadowfrost damage and puts a debuff on the target that improves subsequent Mind Spike damage. The intent of Mind Spike is to fill a niche missing in Shadow DPS, though it may be occasionally useful for healers as well. Mind Spike provides a quick nuke to use in situations where the priest doesn't have time to set up the normal rotation, such as when adds are dying too fast or you have to swap targets a lot. Spamming Mind Spike will do about as much damage as casting Mind Flay on a target afflicted with Shadow Word: Pain. The idea behind the debuff is that when you cast Mind Spike, we expect you to cast a lot of them; we don't intend you to fit it into an already full Shadow rotation. It also provides Shadow with a spell to cast when locked out of the Shadow school. (School lockouts will no longer affect both schools for multi-school spells.) 1.5-second cast. 30-yard range. No cooldown.

Inner Will (level 83): Increases movement speed by 12% and reduces the mana cost of instant-cast spells by 10%. This buff will be exclusive with Inner Fire, meaning you can't have both up at once. Inner Fire provides a spell power and Armor buff; Inner Will should be useful on a more situational basis.

Leap of Faith (level 85): Pull a party or raid member to your location. Leap of Faith (or "Life Grip") is intended to give priests a tool to help rescue fellow players who have pulled aggro, are being focused on in PvP, or just can't seem to get out of the fire in time. Instant. 30-yard range. 45-second cooldown.

Changes to Abilities and Mechanics

In addition to introducing new spells, we're planning to make changes to some of the other abilities and mechanics you're familiar with. This list and the summary of talent changes below it are by no means comprehensive, but they should give you a good sense of what we intend for each spec.

All HoTs and DoTs will benefit from Haste and Crit innately. Hasted HoTs and DoTs will not have a shorter duration, just a shorter period in between ticks (meaning they will gain extra ticks to fill in the duration as appropriate).
We want to bring back Shadow Word: Death as an "execute" -- something you do when the target is at 25% health.
While we want to keep the priest's role as a well-rounded healer, we also want to make sure the class is a viable tank healer, which is something priests moved away from a little in Wrath of the Lich King. Greater Heal will probably be the tank-healing spell of choice, though we've also discussed giving Discipline a second shield so that they have a small shield to cast on lots of different targets, and a big, more expensive shield to cast on a tank or anyone else taking a ton of damage.
Divine Spirit and Prayer of Spirit will be removed from the game. As Spirit will be the primary mana-regeneration stat, we don't want it to vary as much between solo, small group, and raid play. Blessing of Kings and Mark of the Wild will not boost Spirit either.
Mana will be a bigger consideration for all healers. We aren't trying to make healing more painful; we're trying to make it more fun. When the cost of a spell isn't an issue, then casting the right spell for the job is less of an issue because you might as well just use your most powerful spell all of the time. We are, however, getting rid of the five-second rule, because we don't want to encourage standing around doing nothing. We're also going to cut back on the benefits of buffs such as Replenishment so priests (and all healers) don't feel as penalized when those buffs aren't available.

New Talents and Talent Changes

We want to improve Discipline's single-target healing capacity. One key is to make sure shielding isn't always a more attractive option than healing.
We want to improve Holy for PvP healing. One way to do this is to make sure that Heal's throughput is similar between both specs.
We want to improve Shadow for short fights and reduce its susceptibility to school lockouts.
Discipline will finally be getting Power Word: Barrier as a talented ability. Think of it like a group Power Word: Shield.
We want to make Holy a little bit more interesting to play. One new talent will push the Holy priest into an improved healing state when he or she casts Prayer of Healing, Heal, or Renew three times in a row. The empowered state varies depending on the heals cast.
Since the Shadow tree has a lot of passive damage-boosting abilities -- something we're trying to avoid in Cataclysm -- we will need to replace several of the tree's talents. One idea is to play off of the new Shadow Orbs mechanic (see Mastery section below), possibly allowing you to consume an orb to increase damage from Mind Blast or reduce Mind Spike's cast time.
Misery will no longer affect spell Hit chance. We want players to be able to gear themselves around a Hit cap that isn't variable depending on group composition.


Mastery Passive Talent Tree Bonuses

Discipline
Healing
Meditation
Absorption

Absorption: Improves the strength of shields such as Power Word: Shield, Divine Aegis, and Power Word: Barrier.

Holy
Healing
Meditation
Radiance

Radiance: Your direct heals add a small heal-over-time component to the target.

Shadow
Spell damage
Spell Crit
Shadow Orbs

Shadow Orbs: Casting spells grants a chance for Shadow Orbs to be created that fly around you and increase your shadow damage. This will help lower-level characters feel more like "Shadow priests" before they obtain Shadowform.

We hope you enjoyed this preview, and we're looking forward to hearing your initial thoughts and feedback on these additions and changes. Please keep in mind that this information represents a work in progress and is subject to change as development on Cataclysm continues.

A few quick clarifications:

Neither Inner Fire nor Inner Will has charges. The decision is on which armor you want up at the time.

Preventing dot clipping is something we want to do in general. It obviously benefits Shadow priests just as much as warlocks.

The idea behind Mind Spike is that you can't always settle into your normal, and high-ramp up rotation. It's also useful when you have to move or get school locked.

The closest analogue to PW:B is the DK Anti-Magic Zone, but it has some important differences, such as a way to counter it in PvP (since it absorbs all damage, not just magical damage).

The idea behind the Holy "cast three in a row" talent (it's called "Chakra") is that we've always positioned Holy as a versatile healer. This talent lets you shift into different modes. If you need to be a tank healer, cast three single target heals and your single-target healing is now better. Cast three area heals, and you can be a temporarily specialized group healer. We're going to try to play this mechanic up with a cool UI to try to get that "I'm almost in the zone" feel. We'll let it apply to as many types of spells as we can, perhaps even Smite for those times when nobody's taking damage.

We pulled Misery because we are pulling every group benefit that improves hit. It's annoying to have to swap your gear in and out depending on who shows up for your group. In general we're going to push even harder in Cataclysm for bringing people you like to play with, not bringing people who have awesome buffs. The answer to almost every question of "But why would they bring me?" should be "Because you know what the hell you're doing."

Warrior

World of Warcraft: Cataclysm will bring with it several changes to class talents and abilities. Here you will get a glimpse into some of the changes we have in store for the warrior. The information you're about to read is not complete, and is only meant to act as a preview for some of the exciting new things to come.

New Warrior Abilities

Inner Rage (Level 81): Whenever the character reaches a full 100 Rage, he or she will gain a buff that causes attacks to consume 50% more Rage and do 15% more damage for a short amount of time. This is a passive ability so it won't need to be activated by the player. The goal for this ability is to provide a benefit for hitting max Rage instead of it feeling like a penalty. However, we also don't want warriors to feel like they're supposed to pool Rage and do nothing until they hit 100, so we'll be closely monitoring how this plays out during the beta testing, and making adjustments as needed.

Gushing Wound (Level 83): This ability will apply a bleed effect to the target. If the target moves, the bleed gains an extra stack and refreshes its duration, up to a maximum of three stacks. The ability is currently planned to have no cooldown, cost 10 Rage, and have a 9-second duration. Gushing Wound is designed to be weaker than Rend with one stack, but better with three stacks, which will be reached when fighting a moving target.

Heroic Leap (Level 85): This ability makes the character leap at their target and apply the Thunder Clap ability to all enemies in the area when they land. Heroic Leap will be usable in Battle Stance and shares a cooldown with Charge, but the Juggernaut and Warbringer talents will allow Heroic Leap to be used in any stance and possibly while in combat. The cooldown for this ability might be longer than the Charge ability, but it will also apply a stun effect so you can make sure the target will still be there when you land.

Changes to Abilities and Mechanics

In addition to learning new abilities, you'll see changes to other abilities and mechanics with which you're already familiar. This list and the summary of talent changes below it are by no means comprehensive, but they should give you a good sense of what we intend for each spec.

Heroic Strike will no longer be an "on next swing" attack, as we are removing this mechanic in Cataclysm. To keep the niche of Heroic Strike as a Rage dump, it will become an instant attack, but will cost between 10 and 30 Rage. This ability will not be usable until you have 10 Rage, but if you have more than 10, it will consume up to 30, adding additional damage for each point of Rage consumed above the base 10. Other abilities, such as Cleave, Execute, and Maul (for druids) will work similarly. The goal is to provide players with an option where if you can't afford the Rage, you don't push the button, but if you have excess Rage, you can push it a lot.
Battle Shout, Commanding Shout, and possibly Demoralizing Shout will work more like the death knight's Horn of Winter ability. Specifically, these shouts will cost no resources, generate rage in addition to their current effects, and be on a short cooldown.
Whirlwind will hit an unlimited number of targets, but only for 50% of weapon damage. The intent is for this ability to be used in multi-target scenarios and not on single targets.
Overall, heals cast by players in Cataclysm will be a lower number relative to players' health than the current game. So to make the Mortal Strike debuff less mandatory but still useful in PvP, Mortal Strike will reduce healing by only 20%. All equivalent debuffs, including the Shadow priest and Frost mage debuffs, will be for 20% less healing. At the moment we aren't considering giving this debuff to anyone else, though we will certainly consider PvP utility for historically under-represented specs that use other mechanics.
Sunder Armor will be reduced to three stacks instead of five, and still provide only a 4% reduction in armor per stack. We want to make this debuff easier to apply and less of a damage swing when it falls off.


New Talents and Talent Changes

The Furious Sundering talent in the Fury tree will make the Sunder Armor ability cause 25/50% weapon damage and reduce the threat generated by 50/100%.
The Mace and Poleaxe Specialization talents in the Arms tree will be removed. These provided just passive stats, which are not the kinds of talents we want to design in the future. We will keep the Sword Specialization talent, but it will be changed to a talent that applies to all types of weapons.
As a Fury talent, Booming Voice will increase the Rage generated by shouts.
While we like how Titan's Grip plays, we recognize some warriors liked the Fury tree because of the really fast swings that dual-wielding one-handed weapons could provide. Therefore, we're planning to try out a talent called Single-Minded Fury that is parallel to Titan's Grip and will provide a large boost to the damage of a pair of one-handed weapons.
Several talents that reduce the Rage cost of abilities will be changed to focus on increased damage for those abilities instead.
The new Arms talent called Disarming Nature will make successful disarms cause the target to cower in fear for 5/10 seconds.
Another new Arms talent called Blitz will make the Charge ability hit for extra damage. The amount will possibly vary depending on the distance travelled.
Improved Pummel, a Fury talent, will cause a successful interrupt to generate 10/20 Rage.

Mastery Passive Talent Tree Bonuses

Arms
Melee Damage
Armor Penetration
Bonus Swing

Bonus Swing: This is similar to the Sword Specialization talent that is currently in the game, but Bonus Swing will work on all attacks and with all weapons. You have a chance to proc a free, instant weapon swing that hits for 50% damage.

Fury
Melee Damage
Melee Haste
Enrage Intensity

Enrage Intensity: Every benefit of being enraged is increased. This includes doing more damage/healing/ etc. from abilities like Bloodrage, Death Wish, Enrage, Berserker Rage, and Enraged Regeneration.

Protection
Damage Reduction
Vengeance
Critical Block Chance

Critical Block Chance: As we mentioned in the stat changes preview, block rating is changing to a chance to block 30% of a melee swing's damage. Protection warriors have a chance that the block will be a critical block and block for 60% of a melee swing's damage instead. There will likely be talents available to push the amount blocked even higher.

Vengeance: This is a mechanic to ensure that tank damage (and therefore threat) doesn't fall behind as damage-dealing classes improve their gear during the course of the expansion. All tanking specs will have Vengeance as their second talent tree passive bonus. Whenever a tank gets hit, Vengeance will give them a stacking attack power buff equal to 5% of the damage done, up to a maximum of 10% of the character's un-buffed health. For boss encounters, we expect that tanks will always have the attack power bonus equal to 10% of their health. The 5% and 10% bonuses assume 51 talent points have been put into the Protection tree. These values will be smaller at lower levels. Remember, you only get this bonus if you have spent the most talent points in the Protection tree, so you won't see Arms or Fury warriors running around with it. Vengeance will let us continue to make tank gear more or less the way we do today – there will be some damage-dealing stats, but mostly survival-oriented stats. Druids typically have more damage-dealing stats even on their tanking gear, so their Vengeance benefit may be smaller, but overall the goal is for all four tanks do about the same damage when tanking.

We hope you enjoyed this preview, and we're looking forward to hearing your thoughts and feedback on these additions and changes. Please keep in mind that this information represents a work in progress and is subject to change as development on Cataclysm continues.

Death Knight

World of Warcraft: Cataclysm will bring with it several changes to class talents and abilities. In this preview, you'll get a glimpse at some of the new abilities, spells, and talents in store for the death knight class, along with an early look at some improvements we plan to make to the rune resource system.

New Death Knight Abilities

Outbreak (level 81): Outbreak infects the target with both Frost Fever and Blood Plague at no rune cost. This ability allows death knights to apply diseases quickly when they are switching targets or when their diseases have been dispelled.

Necrotic Strike (level 83): Necrotic Strike is a new attack that deals weapon damage and applies a debuff that absorbs an amount of healing based on the damage done. For context, imagine that the death knight can choose between doing 8,000 damage outright with a certain ability, or dealing 6,000 damage and absorbing 4,000 points in incoming heals with Necrotic Strike -- the burst is smaller, but a larger overall amount of healing would be required to bring the target back to full health.

This ability is meant to bring back some of the old flavor from when death knights could dispel heal-over-time (HoT) effects. It also gives the class a bit more PvP utility without simply replicating a Mortal Strike-style effect.

Dark Simulacrum (level 85): The death knight strikes a target, applying a debuff that allows the death knight to copy the opponent's next spell cast and unleash it. Unlike Spell Reflection, Dark Simulacrum does not cancel the incoming spell. In general, if you can't reflect an ability, you won't be able to copy it either.

Rune System Changes

While we're satisfied with the way the rune system works overall, we're making a few major changes to the mechanics that will ultimately help death knight players feel less constrained. Here's the rationale behind the changes, followed by an explanation of how the new system will work.

In the current rune system, any time a rune is sitting idle, death knights are losing out on potential damage output. By comparison, rogues spend most of their time at low energy levels, and if they're unable to use their skills for a few seconds, that energy builds up and can be spent later, minimizing the net loss from the interruption.
A death knight's runes, on the other hand, cannot be used until they are fully active. If a death knight ever goes more than a few seconds without spending an available rune, that resource is essentially wasted. Because the death knight is pushing buttons constantly, it can be difficult to add new mechanics to the class because the player doesn't have any free global cooldowns to use them. We can't grant extra resources or reduced cost, because there is no time to spend them. Missing an attack is devastating, and it's impossible to save resources for when they're most useful.
Additionally, each individual death knight ability has a fairly low impact on its own, making it feel like most of the death knight's attacks are weak. The death knight's rotations are also more easily affected by latency or a player's timing being just a little off. At times, it feels like death knights aren't able to take advantage of their unique resource mechanic, which can diminish the fun.
The new rune system will change how runes regenerate, from filling simultaneously to filling sequentially. For example, if you use two Blood runes, then the first rune will fill up before the second one starts to fill up. Essentially, you have three sets of runes filling every 10 seconds instead of six individual runes filling every 10 seconds. (Haste will cause runes to fill faster.) Another way to think of this is having three runes that go up to 200% each (allowing extra "storage"), rather than six runes that go up to 100% each.
As this is a major change to the death knight's mechanics, it will of course require us to retune many of the class's current abilities. For example, each ability needs to hit harder or otherwise be more meaningful since the death knight is getting fewer resources per unit of time. Some abilities will need to have their costs reduced as a result.


Talent Changes

Next we'll outline some of the death knight talent-tree changes we're planning in Cataclysm. This list is by no means comprehensive, but it should give you a sense of how we're intending each death knight spec to perform.

One of the biggest changes we're making is converting Blood into a dedicated tanking tree. While we feel that having three tanking trees was successful overall, it's less necessary in a world with dual-specialization. In addition, the current breakdown isn't as compatible with the Mastery-based passive talent-tree bonuses we want to add (see below). We'd rather spend time tweaking and balancing one good tanking tree rather than having a tank always wondering if they picked the "correct" tree out of three possibilities.
Blood seemed like the best fit for tanking. Unholy has always had a strong niche with diseases, magic, and command over pets. Frost now feels like a solid dual-wield tree with Frost magic damage and decent crowd control. Blood's niche was self-healing -- fitting for a tank -- as well as strong weapon swings, which could easily be migrated to Frost and Unholy.
Our plan is to move the most interesting and fun tanking talents and abilities to Blood. For example, you will likely see Vampiric Blood and Will of the Necropolis remain, while Bone Shield will move over from Unholy.

Mastery Passive Talent Tree Bonuses

Blood
Damage reduction
Vengeance
Healing Absorption

Healing Absorption: When you heal yourself, you'll receive an additional effect that absorbs incoming damage.

Vengeance: This new mechanic is designed to ensure that tank damage output (and therefore threat) doesn't fall behind as damage-dealing classes improve their gear during the course of the expansion. All tanking specs will have Vengeance as their second talent tree passive bonus. Whenever a tank gets hit, Vengeance will grant a stacking Attack Power buff equal to 5% of the damage done, up to a maximum of 10% of the character's unbuffed health. For boss encounters, we expect that tanks will always have an Attack Power bonus equal to 10% of their health. The 5% and 10% bonuses assume 51 talent points have been put into the Blood tree; these values will be smaller at lower levels.

You only get the Vengeance bonus if you have spent the most talent points in the Blood tree, so you won't see Frost or Unholy death knights running around with it. Vengeance will let us continue to design tank gear more or less the way we do today; there will be some damage-dealing stats, but mostly survival-oriented stats. Druids typically have more damage-dealing stats even on their tanking gear, so their Vengeance benefit may be smaller, but the goal is that all four tanks will do about the same damage when tanking.

Frost
Melee damage
Melee Haste
Runic Power Generation

Runic Power Generation: This will function as the name implies, and the new rune system will make generating Runic Power more appealing.

Unholy
Melee damage
Melee and spell critical damage
Disease Damage

Disease Damage: Unholy death knights will be able to get more out of their diseases, which are integral to the tree's play style.

We hope you enjoyed this preview, and we're looking forward to hearing your thoughts and feedback on these additions and changes. Please keep in mind that this information represents a work in progress and is subject to change as development on Cataclysm continues.

Here are a few points of clarification:

We want to provide a 2-handed style for Frost since we recognize that pets are an acquired taste. We think we have the design space to do that now that we don’t need to support Frost tanking. We’re definitely committed to making Frost work as a dual-wield tree though -- that isn’t going away.
Outbreak is free with a 1-minute cooldown. It’s not supposed to completely replace Plague Strike and Icy Touch.
We’re not sure how we’re going to handle presences yet. We recognize the oddness of Blood death knights playing in Frost Presence and Frost death knights not playing in Frost Presences. We might rename the presences or take some other action.

Rogue

In World of Warcraft: Cataclysm, we'll be making several changes to class talents and abilities across the board. Here, you'll get a glimpse at what's in store for the rogue class, including a look the new high-level abilities and an overview of how the new Mastery system will work with the rogue's different talent specs.

New Rogue Abilities

Redirect (available at level 81): Rogues will be getting a new ability to help them deal with changing targets. Redirect will transfer any active combo points to the rogue's current target, helping to ensure combo points aren't wasted when swapping targets or when targets die. In addition, self-buff abilities like Slice and Dice will no longer require a target, so rogues can spend extra combo points on those types of abilities (more on this below). Redirect will have a 1-minute cooldown and no other costs.

Combat Readiness (level 83): Combat Readiness is a new ability that we intend rogues to trigger defensively. While this ability is active, whenever the rogue is struck by a melee or ranged attack, he or she will gain a stacking buff called Combat Insight that results in a 10% reduction in damage taken. Combat Insight will stack up to 5 times and the timer will be refreshed whenever a new stack is applied. Our goal is to make rogues better equipped to go toe-to-toe with other melee classes when Evasion or stuns are not in play. This ability lasts 6 seconds and has a 2-minute cooldown.

Smoke Bomb (level 85): The rogue drops a Smoke Bomb, creating a cloud that interferes with enemy targeting. Enemies who are outside the cloud will find themselves unable to target units inside the cloud with single-target abilities. Enemies can move inside the cloud to attack, or they can use area-of-effect (AoE) abilities at any time to attack opponents in a cloud. In PvP, this will open up new dimensions of tactical positional gameplay, as the ability offers a variety of offensive and defensive uses. In PvE, Smoke Cloud can serve to shield your group from hostile ranged attacks, while also drawing enemies closer without the need to rely on conventional line-of-sight obstructions. Smoke Cloud lasts 10 seconds and has a 3-minute cooldown.

Changes to Abilities and Mechanics

We're also planning to make changes to some of the other abilities and mechanics you're already familiar with. This list and the summary of talent changes below it are by no means comprehensive, but they should give you a good sense of what we want for each spec.

In PvP, we want to reduce the rogue's dependency on binary cooldowns and "stun-locks," and give them more passive survivability in return. One major change is that we'll put Cheap Shot on the same diminishing return as other stuns. The increase to Armor and Stamina on cloth, leather, and mail gear will help with this goal as well.
In PvE, even accounting for active modifiers like Slice and Dice and Envenom, a very large portion of the rogue's damage is attributable to passive sources of damage. Yes, they are using abilities for the entire duration of a fight, but we want to reduce the percentage of rogue damage that comes from auto-attacks and poisons. More of their damage will be coming from active abilities and special attacks.
We would like to improve the rogue leveling experience. Positional attacks and DoT-ramping mechanics will be de-emphasized at low levels and then re-introduced at higher levels for group gameplay. We are also providing rogues with a new low-level ability, Recuperate, to convert combo points into a small heal-over-time (HoT).
To complement the change to combo points, non-damage abilities such as Recuperate and Slice and Dice will no longer have target requirements and can be used with any of the rogue's existing combo points, including combo points remaining on recently killed targets. This will not affect damage abilities, which will still require combo points to be present on the specific target you want to damage. To coincide with this, the UI will be updated so that rogues know how many combo points they have active.
Ambush will now work with all weapons, but will have a reduced coefficient when not using a dagger. When opening from Stealth, all rogues will be able to choose from burst damage, DoT abilities, or a stun.
As we've done recently with some of the Subtlety abilities, we want to make sure more rogue abilities aren't overly penalized by weapon choice. With a few exceptions (like Backstab), you should be able to use a dagger, axe, mace, sword, or fist weapon without being penalized for most attacks.
Deadly Throw and Fan of Knives will now use the weapon in the ranged slot. In addition, we hope to allow rogues to apply poisons to their throwing weapons.
We are very happy with Tricks of the Trade as a general mechanic and as a way to give rogues more group utility, but we don't want it to account for as much threat transfer as it does now.


New Talents and Talent Changes

In Cataclysm, the overall feel of each of the rogue's talent trees will change, as we would like each tree to have a clearly defined niche and purpose. The talent details below are meant to give you an idea of what we're going for.

Assassination will be more about daggers, poisons, and burst damage.
Combat will be all about swords, maces, fist weapons, axes, and being engaged toe-to-toe with your enemies. A Combat rogue will be able to survive longer without needing to rely on Stealth and evasion mechanics.
The Subtlety tree will primarily be based around utilizing Stealth, openers, finishers, and survivability. It'll be about daggers, too, but less so than Assassination.
In general, Subtlety rogues needs to do more damage than they do today, and the other trees need to have more tools.
Weapon-specialization talents (for all classes, not just rogues) are going away. We do not want you to have to respec when you get a different weapon. Interesting talents, such as Hack and Slash, will work with all weapons. Boring talents, such as Mace Specialization and Close Quarters Combat, will be going away.
The Assassination and Combat talent trees currently have a lot of passive bonuses. We plan to dial back the amount of Critical Strike Rating provided by these trees so that rogues still want it on their gear.


Mastery Passive Talent Tree Bonuses

Assassination
Melee damage
Melee critical damage
Poison damage

Combat
Melee damage
Melee Haste
Harder-hitting combo-point generators

Subtlety
Melee damage
Armor Penetration
Harder-hitting finishers

The initial tier of rogue Mastery bonuses will be very similar between the trees. However, the deeper that a player goes into any tree, the more specialized and beneficial the Masteries will be to the play style for that spec. Assassination will have better poisons than the other two specs. Combat will have very steady and consistent overall damage. Subtlety will have strong finishers.

We hope you enjoyed this preview, and we're looking forward to hearing your initial thoughts and feedback on these additions and changes. Please keep in mind that this information represents a work in progress and is subject to change as development on Cataclysm continues.

Hunter

With the upcoming World of Warcraft: Cataclysm many game elements will be changing, and each class will be receiving a number of tweaks. Here, we will explore the changes that are being made to the gun-wielding, pet-training hunter. The information you’re about to read is certainly not complete, and is only meant to act as a preview of some of the exciting new things to come. Without further ado, let’s take a look at the new hunter abilities!

New Hunter Abilities

Cobra Shot (level 81): A new shot that deals Nature damage instead of Physical damage. This ability will share a cooldown with Steady Shot. This will give hunters an alternative to Steady Shot on heavily-armored targets, and we will have talent incentives in the Beast Mastery tree to make this a signature shot.

Trap Launcher (level 83): When used, the next trap can be shot to a location within 40 yards. This provides the current Freezing Arrow treatment to all traps and, as a result, we will be removing the current ability Freezing Arrow. 1-minute cooldown. No global cooldown.

Camouflage (level 85): The hunter enters an obscured state that prevents him or her from taking ranged damage. The character would still be subject to melee or area-of-effect attacks, and dealing or taking damage will break the Camouflage effect. The hunter can move and set traps when under Camouflage, and will receive a damage bonus when attacking while under Camouflage (which will then break the effect).

Resource Mechanic Change
Here we come to the meat of the upcoming hunter changes.

Hunters will no longer use mana; instead the class will use Focus. Focus generates much like Energy, by building up. It will not be affected by Intellect at all. Haste will improve its generation. Hunters will generate roughly 6 Focus per second, slightly less than rogues' Energy generation rate of around 10 Energy per second. Below, we have listed some examples of how we intend Focus costs to operate:
Steady Shot/Cobra Shot: No cost. Generates 9 Focus per shot (or 12 per second instead of 6).
Arcane Shot/Chimera Shot /Explosive Shot: 45 Focus.
Aimed Shot/Multi-Shot: 60 Focus.
Concussive Shot/Tranquilizing Shot: 35 Focus.
Rapid Fire/Master’s Call/Disengage: 30 Focus.

Changes to Abilities and Mechanics

In addition to the resource change and new abilities listed above, we intend to make adjustments to some of the other abilities and mechanics you already know well. This list and the summary of talent changes below it are by no means comprehensive, but they should give you a good sense of what we’re going for with each spec.

A major change coming for the hunter is the removal of ammunition. Guns, bows, and crossbows will now do damage without consuming ammunition at all. There will be no more ammo slot on the hunter’s character display. Any ammunition that a hunter has at the time of the change will become gray sellable items. Existing quivers will be converted into large bags -- though each hunter can only have one and non-hunters will not benefit from this change -- and we will not be making any additional quivers.
Pet management will also change. Hunters will now have two types of attainable pets: active pets and stored pets. Hunters will be able to have up to three active pets (perhaps five for Beast Mastery specialized players) and will have the ability to switch among these pets any time they are out of combat, without going to town. They will also be able to have a large number of pets in storage at the stables. In order to swap a pet from active to passive, a hunter will still need to visit their local Stable Master. However, this should afford ample storage for the many Spirit Beasts wandering the lands of Azeroth.

Additionally, hunters will now start with a race-appropriate pet at level 1 and will be able to tame a different pet at level 10. We are also changing many pet family abilities to provide important buffs and debuffs. The intention is to allow the hunter to be able to swap pets and fill a position if a certain role is missing from the group. The goal is to have all pets provide a damage increase that is very similar and no greater than any other pet. Some examples of the changes we are making to the pet families are listed below:
Wind Serpents: Will provide a debuff that increases the amount of spell damage taken by an enemy (similar to a weaker version of the warlock ability Curse of Elements).
Ravagers: Will provide a debuff that will increase an enemy's Physical damage vulnerability (similar to a weaker version of the warrior ability Rampage).
Hyenas: Will provide bleed damage (similar to a weaker version of the druid ability Mangle).

Stings and other periodic effects will now benefit from haste and critical strike ratings. Hasted damage-over-time abilities do not lose duration, but instead add additional damage ticks.
Viper Sting will now restore 9 Focus every 3 seconds.
We are reinforcing hunters as a ranged class. To this end, the class will now start with ranged abilities at level 1, and we will be removing some melee abilities, such as Mongoose Bite.


New Talents and Talent Changes

Beast Mastery hunters will have a new talent called Careful Aim, which increases the damage of the next Steady Shot or Cobra Shot, but also increases the cast time of these abilities. The intention is to make the combination of spells into a decent damage opener, especially in conjunction with the new ability Camouflage.
Beast Mastery hunters will also have talents that make Cobra Shot superior to Steady Shot, such as Longevity reducing the cast time of Cobra Shot to 1.5 seconds.
Rapid Recuperation will cause Rapid Fire to give 20/40/60 Focus immediately and will cause Rapid Killing to generate 3 Focus per second.
Efficiency will reduce the Focus cost of Chimera Shot, Aimed Shot, and Arcane Shot.
Thrill of the Hunt grants Focus when you land a critical strike.
Hunter vs. Wild increases the hunter’s Focus generation when his or her pet is snared, stunned, or rooted.


Mastery Passive Talent Tree Bonuses

Beast Mastery
Ranged Damage
Haste
Pet Damage

Pet Damage: Many of the passive benefits to pet damage will no longer be available in the Beast Mastery talent tree. However, these will be provided through the new Mastery mechanic.

Marksmanship
Ranged Damage
Armor Penetration
Double Shot

Double Shot: The hunter will have a chance to launch a free attack off of the global cooldown for 50% damage.

Survival
Ranged Damage
Ranged Critical Damage
Elemental Damage

Elemental Damage: Hunter abilities such as traps, Black Arrow, and Explosive Shot will do elemental damage of the following types: Arcane, Fire, Frost, Nature, and Shadow.

We hope you enjoyed this preview, and ask that you provide your initial thoughts and feedback on what was presented here. Please keep in mind that what you’ve just reviewed is a work in progress and as we move closer to the Cataclysm beta, you’ll see these planned changes as well as others continue to develop in response to feedback and testing.

A clarification of Camouflage and what becoming obscured actually means:
Camouflage is *not* stealth. Your enemies will never wonder where you are. We're trying to use the new Cataclysm water effect to put a shimmering PREDATORy visual on you. It's protection from ranged attacks and it gives you some combat bonuses, but it's not like Shadowmeld or rogue / druid stealth where players can't find you.

The idea with it is that Hunters are only vulnerable to melee attacks or ranged AEs while they are in the obscured state. If you target a camo hunter or a rogue using Smoke Bomb, you will get an error message saying something like "Target obscured." You can see them and target them, but can't use your attacks. Imagine they are behind a pillar or something. You can try and get off an AE near them or you can move to melee.

As most of you know, we tried Camo once before, but because it was true stealth it was very hard to balance, plus it felt like we were just handing out the same cool abilities to every class instead of coming with unique mechanics. Hunters were so overwhelmingly excited about the basic idea that we wanted to try it again, but not as stealth.

Regarding Cobra Shot sharing cooldown with Steady Shot:
At this point in time it's not actually a cooldown. Cobra Shot has a 2 sec cast time, but Beastmaster has a talent to reduce the cast time to 1.5 sec (as well as a few damage hooks). Both generate focus so there is no reason for BM to ever use Steady again.

Regarding focus and how much of it Hunters will have:
Hunters will get 100 focus

The focus costs mentioned in the preview are just examples, so it is a little too soon for you to try to min / max your rotations just yet. In general, the basic rotations of all three hunters work okay on live today. With focus you might hit moments where you don't need to Steady at all, and you'll never run dry again for long periods of time like you might with mana.

If the costs of some of the defensive cooldowns are too expensive or even need to be free that's certainly the kind of thing we'll consider.

Regarding Ammo in Cataclysm:
There is no ammo slot on your character sheet in Cataclysm. It no longer exists.

While we like how Titan's Grip plays, we recognize some warriors liked the Fury tree because of the really fast swings that dual-wielding one-handed weapons could provide. Therefore, we're planning to try out a talent called Single-Minded Fury that is parallel to Titan's Grip and will provide a large boost to the damage of a pair of one-handed weapons.
