I was wondering as an improvement, what about making transformations a permanent thing? I mean you can transform back into yourself if you want. But, whatever you transform into, you take on the role of that school, e.g. Reaper = Death school etc and means you are more vulnerable to life spells.
Also another idea, there are so many things that you can buy with crowns, that I think should be able to be bought with gold, maybe even like once a month we should be able to do this. Otherwise, it seems kind of more money orientated, which is a little sad.
I doubt this will get much look at, but it is out there.
