Wombo combo kills using both charges If you used both firebolt and your melee, you'd also get a kill. Difference is, people couldn't just walk out of a bolt+melee like they can with a wombo, 'cause sunsinger nades are actually GOOD. Voidwall, spike and vortex? 3 area denial nades with slow damage. Unless you find a way to catch players in them, they do nothing, and thus the combo was born. Edit: and no, nightstalker's super isn't much easier to use. It's a pos because the tether delay is obscene.
