Blizzard has released a few small hotfixes that went in place this last Tuesday, January 8. And while we're just hearing about them now, indications are that they are active on the live servers at this time.
Notable is the Vengeance/Attack Power hotfix that counters the extreme level 80 soloing done by a resourceful paladin
The full list is as follows:
Attack Power gained from Vengeance is now capped at the player's maximum health.
Dungeons, Raids & Scenarios
Commander Oxheart in Townlong Steppes will now sell Crystallized Dread, Crystallized Terror, Crystallized Horror, and Eye of the Black Prince for gold to players that have completed the appropriate quest lines.
Completing "Heart of the Alliance" or "A Gathering Storm" will no longer sometimes cause players to be phased incorrectly.
Feng the Accursed now correctly has a chance to drop Fan of Fiery Winds and Feng's Ring of Dreams in the 10 player Heroic mode version of the encounter.
