Depends if I can get a complete spell list that isn't just Fire and Ice.

I do like the idea of prestige classes but I don't think it'll happen. I'm already quite miffed about how misrepresented a majority of the classes are. Scattered spell lists among mages is just the tip of the iceberg IMO.

And I think the whole role of the class will stop Sage from ever happening since Sage was a master of both White and Black magic. And SE wants you to either be focused as a DPS, Healer, or Tank.
