Samurai -dps / Red Mage- dps / Dancer-healer.

I like to see just one dps with a sword as a weapon. Now I know that I didn't include a tank but to me I find them best in the above classes. we still need a tank and it could be a completely new job. SE could come up with new jobs like "white knight" "red knight" and introduce a new weapon with new set of actions. (Special kind of swords or even scythes)
