Because golden gun. I mean, I never use Bladedancer (think I have less than 100 kills with it) but that's because I hate BD. Gunslinger doesn't have any good PvP perks. There's no regen perk, the grenades don't kill despite the pain of aiming them, the only thing we got is triple jump while is purely for jukes! One could argue that throwing knife has 'infinite range' but it doesn't do nearly as much damage or have the utility like any other melee. Even BD melee has regen if you get a kill (because who uses anything else besides Hungering Strike?) while others might give overshields or regen. Sure, you get two of them and you can make them do fire damage but that's buggy as all hell and barely ever works when you need it. I'm really angry about this, wow.
