It's hotfix time! Blue poster Zarhym has posted with a whole mess of new hotfixes, and boy are there some doozies this time around. The changes include loot table adjustments for all raid dungeons, adjustments to the Lunar Festival, and a handful of class changes as well. Some highlights from the list:

Heroic set tokens in raid dungeons have been moved to earlier bosses on 25-player Heroic difficulty (chest from Halfus, legs from Maloriak, gloves from Magmaw, helm from Nefarian, shoulder from Cho'gall).
Elder Rumblerock is now available during the quest "Assault on Dreadmaul Rock" for both the Horde and the Alliance.
In Deadmines, Glubtok's Fire and Frost Blossoms summoned during the encounter no longer grant experience or reputation.
In Vortex Pinnacle, bosses will no longer respawn after a soft reset if players already have a Heroic save.
