I just want scholar back tbh. Other than that, I'd live to see a time mage that could stop time, just for the massive amount of Jojo memes it would inspire. (Though, I'm aware, that would be impossible to balance.)

I'd also be down to have a straight up poison mage. Like summoner, but no pets. Just 5-6 dots and an entire rotation/kit based around those dots and maximizing their damage.
