Blizzard has released today a massive dev blog with preliminary annotated patch notes for the Warlords of Draenor alpha test, which itself was just officially announced yesterday.
The big additions relate to garrisons, stat squish and balancing, talents and Draenor perks, racial traits, crowd control, and yet another major healing revamp. Nearly every class in the game has a hefty entry outlining which skills are being changed and which are being deleted from the game entirely. Sounds as if returning players might be needing that newbie tutorial for Draenor after all. Have a look at your class changes and let us know whether you think you're getting buffed, nerfed, or just set up for another cataclysmic reset of the game's combat meta.
