Job Idea: Blue Mage (Healer)

[Rinuko]

I thought the whole concept of Blue Mage was learning and using monster abilities. O.o

Other than Quina, where'd the cooking concept come in? Was it some XI thing? (I've never played XI.)

The FFV Job, Gau, Relm (to a degree, anywho), Quistis, Kimahri, etc.

Yes. Blue Mage get their spells from other enemies if we look back to the previous FF.
I don't see how this would work as a healer nor don't i think we ever going to see it in XIV. Not like we're used to it anyhow.
