Quote from: Blizzard (Source)

Classes: General

• Vengeance no longer triggers when taking damage from other players.

Druids

• The Balance Druid level 4 13-piece set bonus now also increases the damage of Starsurge by 10% in addition to its current effect.

Hunters

• Aspect of the Falcon now grants approximately 35% bonus attack power.
• Deterrence now also reduces damage taken while active by 30%.
• Black Arrow now pulses every 2 seconds for 20 seconds, up from every 3 seconds for 15 seconds. The total damage dealt by this ability has not changed.
• Arcane Shot no longer benefits or consumes Block and Charge.

Magi

• Fireball's damage has been reduced by approximately 6%.
• Pyroblast's initial damage has been reduced by approximately 6%. The damage over time has not changed.

Paladins

• Holy Radiance now consumes 40% of base mana, up from 35%.

Priests

• Mass Dispel should once again prefer to dispel targets that have dispellable magic effects.

Rogues

• Adrenaline Rush no longer triggers a global cooldown.

Dungeons and Raids

• You can now form bands of the same faction with friends with real ID, allowing you to enter the band finder with groups of more than 5 players, make old bands in normal or heroic mode, and participate in battlefields. Cannot perform Dragon Soul in normal or heroic mode with raids between realms of real ID friends.
• Fixed various misprints and improved some descriptions in the Dragon Soul texts of the dungeon guide.
• Players can no longer obtain multiple copies of the same item by killing a boss only once in Raid Finder. For example, a player who out of necessity rolls for two set piece marks or two weapons and wins the first, will not be eligible for the second with that particular boss.
• Baradin Bastion
  • Hideous creatures serving Alizabal have replaced Occu'thar's wandering eyes.
• Dragon soul
  • Yor'sahj the Watchman
    • The Unleash Life shaman spell now works correctly and triggers Profound Corruption only on its target. It used to affect both the caster and the target.
  • Blackhorn Warmaster
    • Twilight elite units' Blade Charge visual warning should be easier to see.
  • Spine of Deathwing
    • Burning Sinew health reduced by 15% in 10- and 25-player Heroic Mode. This change reduces the damage spike required to complete the encounter, allowing players to form raids with more varied builds.
  • Deathwing Madness
    • The Leap of Faith Priest spell can no longer be used while under the effects of Transporter Winds.

Objects

• Shadow Vial (Lightning Strike) damage has been reduced to approximately one third of its previous damage. However, it will now activate approximately 3 times as often. The intention is to keep the overall damage the same while reducing the instant damage spike, especially in PvP.
• The effect of Maw of the Dragonlord can now be activated when using Holy Word: Sanctuary.

User interface

• Fixed a bug that caused the Adult Language Filter to reset when exiting.
• A prompt is now displayed 15 minutes before the player is disconnected using parental controls.
