Most Gunslingers die in their Super due to lack of player skill and awareness. It needs 0 buffs outside of PvE, and that's only accounting for 6-shooter. And maybe even fixing the exploit that allows it to 1-hit body other Supers in PvP, though it'd make the select few who choose to do so(especially if they've remade a character for it) very angry. But that was never intended in the first place. This is coming from someone who mains Hunter.
