Voidwalker ftw. I just love the speed and power combo, living on the edge. Scatter grenade + Shatter + Annihilate + Bloom = MICHAEL BAY EXPLOSIONS!! Also, I feel like few run without Life Steal, but if you do then Surge is EXTREMELY rewarding. It's like being able to move and reload as fast as a Hunter but having the power of a Warlock at your fingertips. Obsidian Mind really helped out with making Void more playable too, and I don't even use Bad Juju with it anymore as it's almost unnecessary. Get plenty of headshots and use your grenade and your super will already be back so fast it's insane.
