December 21

Hunter (Forums / Cataclysm Talent Calculator / Beta Skills/Talents)
•Hunter pets now benefit from the 1% increased hit chance from the Draenei racial Heroic Presence.
Mage (Forums / Cataclysm Talent Calculator / Beta Skills/Talents)
•Flame Orb is now benefiting from Clearcasting procs, is not costing any mana when using the buff, and removing the buff correctly when used.
Paladin (Forums / Cataclysm Talent Calculator / Beta Skills/Talents)
•Damage dealt to the paladin by Hand of Sacrifice correctly breaks all forms of a mage's Polymorph.
•Light of Dawn is now properly locked out when the Holy spell tree is locked out and cannot be used for the duration of the lock.

•The Soulburn effect can now be used on alternate spells if the first attempt to use the Soulburn effect fails.
•Warlocks should no longer get an “Invalid Target Error” when trying to summon a player into a raid instance. If the player is ineligible to enter the instance, they will get an error that they are already locked upon accepting the summon.
Warrior (Forums / Cataclysm Talent Calculator / Beta Skills/Talents)
•Bladestorm now deals 150% normalized weapon damage as advertised. It was incorrectly dealing 100% normalized weapon damage.
Dungeons & Raids
Blackrock Caverns
•The duration of the Superheated Quicksilver Armor debuff on Karsh Steelbender is now 17 seconds, up from 12 seconds. The encounter was too hard to tank and went against our intended fight mechanics. The display for this buff may not properly update until a client-side patch is applied.
•Rom'ogg Bonecrusher's Chains of Woe should no longer push players under the world.
Blackwing Descent
•Magmaw's Pillar of Flame now prefers targets further than 15 yards away for Lava Parasites and will not be cast more than once per 30 seconds.
•Lava Parasites now only apply their melee attack proc to players who are targeted. Lava Parasites are functioning normally and cannot infest a player with more than 3 Parasite debuffs active. Snared Lava Parasites will function like other creatures and switch to a nearby target if it becomes available, making them a viable target for Infestation.
•Drakonid Chainwielders and Drakonid Drudges had too many hit points in the 10-player version. Their hit points have been reduced.
•Drakonid Drudges will charge another target if the furthest target is more than 80 yards away.
Gnomeregan

•Engineers are no longer able to use the Spinal Healing Injector or Z50 Mana Gulper tinkers in Arenas.
•Rare Archaeology finds should now grant triple skill gains.
•The progress on the guild achievement That's a Lot of Travel Time no longer goes up each time players complete the repeatable quest "Could I get a Fishing Flier?"
PvP
Arenas
•All 28 of the Vicious Gladiator 2200 rating weapons now require level 86 to equip. This is a temporary fix to prevent items which were obtained prematurely due to a bug causing Arena rating inflation from being used.
•All weapon, ranged, and off-hand items which require a 2200 rating have been temporarily removed from their respective vendors. This is a temporary fix to prevent items from being obtained prematurely due to a bug causing Arena rating inflation.

•Cadaver Collage's hit points in Crucible of Carnage have been increased. The poison clouds that are left on the ground now despawn when Cadaver Collage begins casting Inhale. When Cadaver Collage begins to float away, it now displays an explosion animation after a few seconds and the player is removed from combat. This occurs within a few seconds, much faster than it previously took to leave combat.
