sounds like an excellent idea to me as long as the bonuses that each character type give are posted and not hidden like so many other details in this game. I don't wanna choose a type and be stuck with something for 10 levels that I don't like. also, it doesn't only have to be stats that change.
for example,
thief - 20% better chance to succeed at crimes.

also, I think you should have to pay to change you character type even at the milestone levels. should take say 10*(you level)^2 dollars and 2*(your level) energy. just something as an incentive not to change.
