I like elementalists, but blue mages are actually scary if made properly. Anything that isn't a Malboro and can use Bad Breath is scary. Fire whip is neat, since it gives damage and disable, but I actually worry when I fight malboros because they can hit you with like 2-8 different status effects with one attack, and one of those effects is Frog, which outdoes disable any day. And you can't ever actually get a monsters as a character walking around, although a morpher makes me laugh so hard when he does that "scary-posture" and is by far the coolest job, with the exception of the aformentioned blue mage. Morphers are the coolest not-a-moster-and-yet-a-monster-anyway classes around.
