If Relm counts, then Pictomancer. Making attacks with the power of art? Awesome! Unfortunately her Sketch skill wasn't very useful, but it sure was a nice idea. I always hoped they'd remake this job class for a later game.

Otherwise, White Mages/Devouts/Seers. They have kitty ears! I probably like FFTA2's version the best, since they give you Magick Frenzy, and hitting the entire field over the head with books/staves is tons of fun.
