Bueno empiezan los cambios en la 4.2.
Classes: General
Crowd Control
Many crowd control abilities no longer cause creatures to attack players when they are cast. The creature will not attack the player when the crowd control wears off, and nearby creatures will not become hostile to the player either. However, if a visible player gets too close to the target creature, the creature will remember and attack the player when the crowd control effect wears off. The intent is to make it easier for dungeon groups to manage crowd control assignments and pulling packs of hostile NPCs. The abilities affected by this change are: Hibernate, Entangling Roots, Wyvern Sting (will still cause hostility when it begins to deal damage), Freezing Trap, Polymorph, Repentance, Shackle Undead, Blind, Hex, Bind Elemental, Banish, Seduction.
Druid (Forums / Talent Calculator / Skills/Talents)
Druids now gain 1 attack power per point of Strength, down from 2. They continue to gain 2 attack power per point of Agility while in Cat Form or Bear Form.
Entangling Roots and the equivalent spell triggered by Nature's Grasp no longer deal damage.
Innervate now grants an ally target 5% of his or her maximum mana over 10 seconds, but still grants 20% of the druid's maximum mana over 10 seconds when self-cast.
Balance

Moonfire now generates 8 Solar Power for druids with Eclipse.
Sunfire now generates 8 Lunar Energy for druids with Eclipse.

Retaliation, Recklessness and Shield Wall no longer have stance requirements.
Dungeons & Raids
Dungeon Journal is in the process of being implemented. While some UI elements may exist in the current Public Test Realm build, the feature is not yet complete.
Guilds
The Reins of the Dark Phoenix, purchased from the Guild Vendor, has had its art improved. It's now less transparent and indisputably more awesome.
PvP
Battlegrounds
Eye of the Storm has been added into the rotation as a 10-man Rated Battleground. The tug-of-war style capture points have been replaced with Arathi Basin style capture points to better support 10v10 competition. This change applies only to Rated Battlegrounds. Eye of the Storm is otherwise still a 15-player Battleground with tug-of-war style capture points.
War Games
Many improvements are being made to the War Games interface, though the changes are not yet fully functional.
User Interface
Characters can now be reorganized at the Character Selection screen. This feature not yet fully functional and the reorganization of characters doesn't save at this time.
The cast bar can now be moved to display below the Character frame.
Move Pad is a mouse-click interface for movement which is now built into the base interface.
Por fin las habilidades "potentes" del warrior no necesitan de una stance especifica. Y ring casteado al fin.
