suggestion: split magic from other level up perks
it always pains me to have to choose between a magic level and a new perk during level up. since this game is about _magic_, wouldn't it be a wise idea to let you choose both a magic level and a perk during level up. perhaps only give the choice between 2 magic levels and 3 perks, or downtone the perks a bit, but it would put a lot more magic for me in the game.
since i've never even gotten a sov above lvl 12 i don't quite see this as ballance affecting, and it gives you a reason to keep your early low lvl heroes around and active since they can still be used end game.
oh, and i second the idea of having a way to remove injuries, either during lvl up or some powerfull spell. you,ve got curse city which can't be undone, celerity destiny's blessing, why no "fix hero?"
