- Bear-ly Made It (new achievement): Save all four prisoners before they are sacrificed in Zul'Aman on Heroic difficulty.
- Players are once again free to dance in combat (without causing graphic errors). Other animations, such as attacks, will take precedence over dancing. The dance animation will be suppressed until the higher priority animation is complete. Fun has been unnerfed.

Glyphs
- Glyph of Ferocious Bite has been redesigned. It now causes Ferocious Bite to heal the caster for 1% of maximum health for each 10 energy used.

Holy
- Denounce has been redesigned. It still reduces the mana cost of Exorcism. However, it no longer has a chance on Holy Shock of making Exorcism free and instant. Instead, it has a 50/100% chance to prevent the Exorcism target from causing critical effects for the next 6 seconds. This effect can be dispelled.
- Holy Shock mana cost has been decreased to 7% of base mana, down from 8%.
- Holy Shield now increases block chance by 5% while active, instead of increasing the amount of damage blocked by 10%.
- Selfless Healer can no longer be dispelled and cannot be stolen via Spellsteal; and, in addition to its current effects, it lowers the cooldown of Word of Glory by 5/10 seconds.

- Devouring Plague damage done has been decreased by 12%.
- Mind Blast damage done has been increased by 12%.
- Shadow Word: Death damage done has been increased by 12%.
- Shadow Word: Pain damage done has been decreased by 12%.
- Mind Flay damage done has been increased by 12%.
- Vampiric Touch damage done has been decreased by 12%.

- Drain Life's damage has been reduced by approximately 25%.
Deadmines
- Vanessa VanCleef (Heroic difficulty) now has a sweet, sweet voice to accompany her dialog.
Set Bonuses
- The 2-piece resilience bonus from Cataclysm PvP sets no longer stacks. If a player wears 2 pieces each from 2 different Cataclysm sets, the player will only receive the 400 resilience rating bonus once. This change does not apply to PvP sets from prior expansions.
Jewelcrafting
- The shield block value bonus from Eternal Earthsiege Diamond has been increased to 3%, up from 1%.
Armor Sets - Druid Tier 12
The gloves still look a little weird and the light effects might be a little off (color-wise) but it should be ok now.
