This may have been suggested before but I'm going to state my opinion.
I don't like having to have sunder and trip on my cleric yet they come with the class. I don't use them at all because she is a caster cleric. If I were to role play her, she wouldn't have aquired that knowledge at all. She would have aquired the knowledge that pertains to what her interists were as a cleric.
I would like to be able to at least switch those feats out for something more appropriate to what she does. A visit to Fred to be able to rid myself of feats that I did not get to choose at character creation would be an acceptable way of allowing this. Better yet, allow us to choose the feats that we want to use at creation instead of saddleing us with feats that we will never use and did not get to select.
