• The existing /welcome emote now greets/welcomes targets (character says “hello”), while the new /yw is for saying "you're welcome."
• Many of the tail sweeps with knockback effects will no longer hit players’ pets.
• Taunt Diminishing Returns: We’ve revised the system for diminishing returns on Taunt so that creatures do not become immune to Taunt until after 5 Taunts have landed. The duration of the Taunt effect will be reduced by 35% instead of 50% for each taunt landed. In addition, most creatures in the world will not be affected by Taunt diminishing returns at all. Creatures will only have Taunt diminishing returns if they have been specifically flagged for that behavior based on the design of a given encounter.
• Pet Resilience: All player pets now get 100% of their master’s resilience.
• Area-of-Effect Damage Caps: We’ve redesigned the way area damage is capped when hitting many targets. Instead of a hard cap on total damage done, the game now caps the total damage done at a value equal to the damage the spell would do if it hit 10 targets. In other words, if a spell does 1000 damage to each target, it would hit up to 10 targets for 1000 each, but with more than 10 targets, each target would take 1000 damage divided by the number of targets. 20 targets would be hit for 500 damage each in that example.

Death Knight

• Scourge Strike: Redesigned. The base ability now deals 50% weapon damage plus an additional amount as physical damage. However, for each disease the death knight has on the target, the target will take additional shadow damage equal to 25% of the physical damage done.
• Unholy Blight: This talent now deals only 10% of Death Coil damage as a damage-over-time effect on the target.

Hunter

• Call Stabled Pet: Cooldown reduced from 30 minutes to 5 minutes.
• Deterrence: Now also increases the chance for ranged attacks to miss the hunter by 100% while under its effect.
• Pets
  • Avoidance: This talent has been replaced by Culling the Herd. Hunter pets now innately take 90% less damage from area-of-effect abilities like all other class pets. This does not apply to area-of-effect damage caused by other players.
  • Cower: Redesigned. This ability no longer affects threat, and instead reduces damage taken by the pet by 40% for 6 seconds with a 45-second cooldown. While cowering, the pet’s movement speed is 50% of normal speed. Cower now only has a single rank and is available at pet level 20.
  • Culling the Herd: This pet talent has replaced the Avoidance talent in the pet trees (Hunter pets now gain that benefit automatically without expenditure of talent points). Culling the Herd increases pet and hunter damage by 1/2/3% for 10 seconds each time the pet deals a critical strike with Claw, Bite, or Smack.
  • Demoralizing Screech: The attack power reduction from this ability has been increased by 40%, equaling the maximum possible attack power reduction from the abilities of other classes.
  • Improved Cower: Redesigned. This ability now reduces the movement penalty of Cower by 50%/100%.
  • Venom Web Spray: Range increased from 20 yards to 30 yards.
  • Web: Range increased from 20 yards to 30 yards.
  • Wolverine Bite: This talent is now enabled when the pet lands a critical strike rather than from the target dodging the pet’s attacks. In addition, this talent no longer has a prerequisite.

Paladin

• Divine Guardian: This talent no longer increases the amount of damage transferred to the paladin from Divine Sacrifice. Instead it causes all raid and party members to take 10/20% reduced damage while Divine Sacrifice is active.
• Divine Sacrifice: Redesigned. The effect of Divine Sacrifice is now party-only and the maximum damage which can be transferred is now limited to 40% of the paladin’s health multiplied by the number of party members. In addition, the damage transferred to the paladin is now reduced by 50% before being applied to the paladin. Finally, the bug which allowed Divine Sacrifice to sometimes persist despite reaching its maximum damage has been fixed. Divine Sacrifice will now cancel as soon as its maximum damage value is exceeded in all cases.

Rogue

• Vanish: For the first half second after this ability is used, neither Vanish nor Stealth can be broken by taking damage or being the victim of a hostile spell or ability.

Warlock

• Improved Felhunter: This talent now also reduces the cooldown on the felhunter’s Shadow Bite ability by 2/4 seconds.
• Decimation: Redesigned. When Shadowbolt, Incinerate or Soul Fire hit a target that is at or below 35% health, the cast time of Soul Fire is reduced by 30/60% for 8 seconds. Soul Fires cast under the effect of Decimation cost no shards.
• Demonic Pact: This talent now also increases the warlock's spell damage by 1/2/3/4/5%.
• Conflagrate: Redesigned. This talent now consumes an Immolate or Shadowflame effect on the enemy target to instantly deal damage equal to 9 seconds of Immolate or 8 seconds of Shadowflame, and causes additional damage over 3 seconds equal to 3 seconds of Immolate or 2 seconds of Shadowflame.
• Doomguard/Infernal: These pets now innately have Avoidance like all other warlock pets.
• Shadow Bite: This pet ability now provides 15% increased damage for each of the warlock’s damage-over-time effects on the target.

Mining

• Enchanted Thorium: This ability now uses the Mining skill and is learned from trainers at a skill level of 250.

Quests

• Weekly raid quests are now available from Archmage Lan'dalock in Dalaran. Every Tuesday at 3 AM the Council of Six will choose a different strategic target that must die from either: The Obsidian Sanctum, Naxxramas, The Eye of Eternity, Ulduar, Trial of the Crusader, or Icecrown Citadel.
• For the various Icecrown Bomber quests at Aldur'thar: The Desolation Gate, players can now choose to eject from their bomber seats mid-run. If you do so, a rescue vehicle will transport your character back to the safety of your infra-green platform.
• Azure Drakes and Dragons will now attack back when attacked by characters not riding Wyrmrest Defenders.

Items

• Death Knight Tier-9 4-Piece Bonus: This set bonus no longer grants Frost Fever a chance to be a critical strike. It still grants that possibility to Blood Plague.
