I don't know if anyone has noticed yet, but right on the Home Page of MMO Champion, near the bottom of the Q&A from Blizzcon there is a statement that says " Destro DPS is Fine at LVL 100 ". I can only assume someone from the crowd asked them if Warlocks could expect any buffs or tuning.
I guess we can still hope for those DEMO buffs
Maybe too many people rolled lock last xpac and they are trying to get people to quit. It's starting to look rather grim.
