In theory charm magic could be great fun, but it suffers the problem that it's pretty much save or suck to save or die. You can get singed by a fireball, but casting Dominate Person is a little binary and could get frustrating quickly. But that's just my two cents on the issue. Mind, illusions are fun :T.

...and I vote for random magic, but that's because I'm an asshole who likes creative constraints and wanted to play the guy who can't use magic anyway
