In this official Blue Post Blizzard announces the Classic Beta will have its level cap raised from 30 to 40 in order to test high level zones like STV, Desolace, Arathi Highlands, and more. On top of this they will be reducing respec costs 99% down to 1 silver in order to assist efforts in testing stuff out. Lastly Arathi Basin for anybody above level 20 will also be out.
Maybe this means more invites? One can hope
