Some ideas:
Barbarian - No magic.
Ranger - Specialise in bow skills.
Dancer - Weilds a dagger and uses primarily Suvivour skills and body or teleportation magic. Supernaturally agile.
Necroancer - Specialise in spells of resurection and summoning.
Paladin/Knight - Must do good, even if it means turning down quests. Must uphold the law and never perform criminal acts.
