[Tyhm]

Graal - Defense - Check, they have the shield, and the Judgement technique
Ninji - Offense, Swordsmanship - Not really, Ninja Stars are cool but not all that Swordsmanlike. Parry is though.
Zorbi - Peace. Check and check.
Lunaris - Exploration. Not really, the respawning advantage is handy but the nuke strike isn't very explorery for all its coolness.
Dragoon - Sparring, Swordsmanship - Check on both, they got a sword technique and the strafe thing, buuut it's a bit much like Ninji...Strafe was originally theirs....
Sardon - Magic. Check and check.
Gaia - Archery. Check and check.
Vampires - more PKing? - automatically gain health when next to the bleeding, dash across the room, but they need more of a unique identity than cool weapons
Lizardon - PKing and evil - Baddy Form, regeneration and Protection from Baddies, what more could you possibly want? ^_^
