Time mage would be my second choice, but they don't have enough offensive spells. Meteor as a time spell is kind of silly.

Why no BLU love? We have offensive (damage of all types, even 100% guaranteed damage in 1000 Needles), defensive (Mighty Guard), curative (White Wind), and other surprises in our bag of tricks (let's see how good your spells hold up after you eat a few Magic Hammers). Plus we're good with swords (better than Red Mage).
