Different classes for different playstyles. I have all 3(duh) and use them all for different reasons. Started warlock originally because I like to be a mage, but then I realized everyone kinda had magic of their own. Titans can wreck teams and bubble down to piss people off or to stay alive. Or come around a corner with a flying kneecap to the head. Throwing Zeus' hot discharge at your terrified squeamish ass...shocking you again...and again... Hunters go invisible and slice the ever living hell out of you. Or they just cross map golden gun you in the face and you explode- killing the person next to you. Noob. Warlocks are sort of the hybrid stepchild of the other 2 classes. Nova galore and scatter nades. Self res in trials tied 4-4 just to get sniped in the face and lose it for your team. -__-
