Two things that have slightly irritated me in many crpg games have to do with leveling and experience.
* Experience inflation; A simple task earns you 5 exp at level one, a similar task may earn you 5000 at level 15.
* Ability and damage inflation: Sometimes it just gets ridiculous (diablo 3, going from hitting 3 dmg, to billions in a single strike)
I understand the allure to develop from a young aspiring adventurer to a demigod during a game, but maybe make it less steep?
There are still a big difference in skill between an average lad and a heavyweight champion, but not thousandfold.
