For me, here are my roles when I play as one of my classes. Preferably Warlock. Here it is, how I play PvE. Hunter = Medic (Blade Dancer) Titan = Goliath with a shield (defender) Warlock = Guy in front killing things with a giant purple ball (Void Walker) For those questioning the role of medic in the Hunters abilities. It's because my Hunter has invisibility. "A great medic is a medic who cannot be seen" MEDIC!!!
