Nova bomb, splinter nade, the truck load of good void weapons (sometimes they count sometimes they don't there is NEVER a -blam!-ing indicator) and i'm going to be that guy but if you have friends just group up and take turns dealing the final hits with void it's shit, but so is any pvp quest if you don't then good luck getting a group where there isn't that one -blam!- that keeps taking the kills Also nova warp gave higher mobility and lasted a while then any other transformation supers so that's a longer time killing things and transformation supers are already pretty annoying to deal with in pvp
