In Drak Tharon in the entrance hall are those soulmages doing those shadow voids. I normally kill the soul mages first and dont have a real problem with those, but sometimes even after all soul mages dead still a lot (really a lot) of those voids appear. The only living mobs today were the Scourge Reanimatore and the Risen D. Warrior. They dont have those abilities, where do the voids come from then? That is a bug, isn't it?
