I agree with a Pirate gambler of some sort. Dual wield sabers. DK melee combo. Jump out to dual wield pistols from ranged for second combo. Like a reverse red mage.

Build up momentum to roll your dice like Setzer, have the different effects be support based for the party, kinda like what Dancer does. I dunno, I just like the idea of wielding swords, guns, and rolling the dice. Maybe some sort of slot machine mechanic.
