I'm an aggressive type. So I always go for the most damaging class. Who keeps his distance, that's the hunter. In an MMO, I've always played better with an archer. But if there is a stealth type, I use it. I find myself doing better with Voidwalker than sunsinger on the warlock. And better with striker than defender on titan. Gunslinger and bladedancer are both the same to me. But I prefer gunslinger.
