Ninja uses daggers but some of them in this game are as long as swords. As for play style they are a bit different though.

Monk uses his fists but some of the later fist weapons can look like swords/claws if you like that sort of thing.

If you like Warriors move set and how they play, unfortunately the dps is not like that as they require positionals. Dragoon may be the closest as far as watching big numbers and attack speed go. They use a Lance though.
