World of Warcraft Patch 5.2: The Thunder King - PTR notes now available
Blizzard has released the preliminary patch notes for Mists of Pandaria's update 5.2, The Thunder King, on the Public Test Realm.
The patch is now available for testing, and when you log in, you'll be able to try out a rather large, new raid dungeon, a new multi-faceted quest hub, Pet Battle improvements, new world bosses, "significant class balance changes," new pets and mounts, and other goodies along with the usual bug fixes and tweaks.
Full notes are available through Battle.net.
