Samurai as a tank. Uses wind based techniques to position self and enemies, along with a dash similar to MNK's shoulder tackle, but places them behind the enemy. JOB itself add's Kiai's; shouts that either damage or weaken enemies, buff allies, or restore HP/TP.

Dark Knight as DPS. Uses own HP as a resource in addition to TP. Possibly have one or two attacks that deal more damage depending on how low HP is. Possibly the most risk/reward class in the game.

Orator as DPS. Fights with both guns and inspiring words. Able to debuff enemies or seduce them to your side for a short period. Won't work on bosses, but could turn add's into a small army.

Dancer as Healer: Dances us better! Fights in melee, giving damage done as healing (like Monk or disc priest in WoW), or sit's back and dances to keep everyone up.
