(Super mild 6.0 alliance raid spoilers? Not sure how to mark spoilers).

My theory is that there'll be a new casting job and Krile will be our showcase character for it. I think they've said that Krile is going to be on our new scions-equivalent team in 7.0, and in the Euphrosyne raid story she wandered off and seemed to be poking around at natural power sources and had a line about how she felt weak and was hoping to get stronger. Something like a geomancer, maybe? Green mage, time mage? I don't think she'd ever be a physical combatant.

Then I bet we get a second job that can share Scouting gear, just so ninja isn't alone there.
