I agree, a mage take option if done right could be a lot of fun. And I agree with XanderOlivieri, a red or blue mage could be used as just that a spell sword. I think a red mage would have more options, and could use en spells which raise their def etc. Could be fun, I'd give it a shot.

Regardless of what party role was needed. I think having a Red Mage, blue mage, time mage, and any other mage, along with other physical classes would be a huge boost. Looking forward to when we can start seeing new classes in the game.
