Maybe it's time to add this section? People who have beta access may be able to contribute early so we can level faster when WoD hits. Just a thought.
kick already has some profiles made for wod, and the wod build is for internal testing only so only the devlopers are testing with it.
I think Brodie seems to have added a big part of the leveling in WoD already as well, same as Kick. Though like Hobo said, think we'll have to wait for a stable release, not sure if we are gonna get it before WoD officially comes out though (not that I read up about it).
There is no special WoD build... The version u have now will just get more stable, unless Blizzard decides to patch/fix more stuff. With the patch 6.0 the game was made rdy for WoD and the API changes were introduced by Blizzard. Everything since then is fixing shit (both Blizzard and HB staff) and making sure its stable for the opening of new zones at midnight (i guess).
