TBH, I think thief is going to be the class? I'm not sure, but that's what it feels like to me. Thief the class and Ninja the job, with Thief DPSing and Ninja Tanking. I don't think they'll introduce another class with two job tiers.... Mostly because there'll be too many DPS classes if they do that, and that might unbalance the game, especially since they're also introducing the Musketeer class or job?
