I was thinking more along the lines of enforced themes with level-ups. Spiderman would start with the ability to climb walls, but could get better at it as the game progressed: faster, gaining the ability to tumble on vertical surfaces, neat new wall-climbing stunts.
I do like your idea of level-ups limited to non-spellcasting classes though. That has some interesting potential.
