Warlock all the way. Primarily a Voidwalker at the moment. Expanded, long-duration Vortex Grenade for locking down entry points and clearing Control bases, triple-shot Nova Bomb for wiping out enemy frontlines. Focused Control on my jumping for aerial cat-and-mouse duels and drop-in fake-outs. Shotgun and Energy Drain melee combo is devasting in the Crucible. I'm going to start levelling up my Sunsinger sub-class soon though, to bring a barrage of that sweet, sweet support action to the team. I'm building a Hunter at some point too. I'm already stockpiling decent gear for him/her in the Vault.
