Perhaps once or twice per game, there should be a chance to respec at least one of your feats. Considering the game is very combat-centric, and one's character build is a huge part of the game, those of us who are not complete masters of the game mechanics would love to be able to earn a respec, even just one feat once per game. Cannot think of any reason it shouldn't be in there, other than perhaps elitism. There could be a quest to earn it, a level requirement, or just throw it in there quick n dirty.
