Blue Mage tank???

[TaiyoShikasu]

snip.

"Hey, let me find literally the worst looking tank set in the game and use it to justify why a spellcaster can't tank."

Also, any new job would likely be starting well above the point that set and its variants are even worth using outside of really bad glamour.

Blue mage learns abilities from monsters etc etc. They should make it a wildcard class, where it can pick up any configuration for any roll. Tank, Healer, or Dps.
