Best mage class?

F/P, I/L, Evan or Luminous are the 'top' for bossing and training. Battle Mages are good, but since they don't ignore elemental resistance they fall behind at high level bosses. Personally I can't stand F/Ps, despite being the strongest theoretically (and probably in practice too, if you know what you're doing), because most of the attacks are rather slow/irritating to use. I'd either go with I/L or Luminous, cool (ha) animations, good at bossing and training and both pretty strong.

If Evan had a proper revamp (updated animations mostly) I'd say go with that, but most Evan skills look pretty bad now compared to newer classes. They are strong and rather fun though.
