Time Mage

[Risvertasashi]

I'm unsure if you've done your research, but Time Mages traditionally employed regenerative effects and used space magic. There is actually a Job in the game with this flavor and that also can toy with time itself. While it lacks a certain signature ability, it possesses quite a few other time magic abilities. Just a subtle hint.

He mentions this right in his opening XD

I wouldn't mind seeing something with some non-RNG utility (And Refesh sounds pretty neat!), but as a pragmatic outlook... there's probably too much overlap for SE to really consider it, yeah.
