Hunter - can use special skills that do extra damage to specific species.
might also have some nature things going on, not sure
Archer - has various bow skills, hit/crit up skills, and situational skills. (deals higher damage to monsters with high def, etc)

I would do a rogue/assassin, but what would be the difference between them and a ninja? If it's different enough, I'll add them. XD

Also, paladins are awesome, but with a knight/dragoon/magic knight, all capable of wearing a 'white tome' for white magic/healing, I'm not seeing a point in that? unless I'm missing something. XD
