I think everyone expects that any new jobs branching off of Gladiator and Marauder will be DPS.

The first ability of any such jobs would likely be a stance that reduces their enmity generation, though its possible that the second job branching off of Marauder wouldn't need it since Marauder does have combos without any enmity modifiers tied to them.

The thing that I'm more curious about is how they will deal with the issue that these likely DPS jobs will be able to wear the best defensive gear in the game (assuming that defense does something in this game). I kind of expect the new Marauder job to be Berserker and that their DPS stance will reduce their defense. Though I gues Beastmaster is another possibility.
