Not just class, but subclass. All of the hunter subclasses seem to be able to fit the bounty hunter, but also titans kinda remind me of a more heavy armor 'mercenary' bounty hunter. I am also referring to Star Wars, and i don't really see warlock as a bounty hunter, they are too much like a Jedi or Sith (Stormcaller could be called palpatine and everyone would know what it does) For me, i think the smoke bombs of nightstalker are some gadgets a bounty hunter would use, but at the same time Gunslinger seems to fir bounty hunter very well.
