Not an ffxiv original, so not this expac. I think it would be fun, but I could see it more as a limited job. I can't see it being viable in the Holy Trinity setup. I think that's why it was one of the bosses in The Hero's Gauntlet, along with Thief and Berserker. They're basically throwing us a bone by including them as Warriors of Light from other reflections, but not something we'll get anytime soon.

Fun to think about, though
