Feats may be optional, but Fighters are gimped without them. So yeah, if you play without feats and complain Fighters are gimps, you are right and the solution is obvious.Feats are optional and classes that are specialists in skills get expertise.
I think there was a thread around here somewhere where these things got pointed out but I can't quite recall which one.
As for expertise, fighters don't get it by default, and rogues don't get a Combat Style by default. So yeah, rogues can fight but fighters fight better, fighters can use skills but rogues can use skills better. The difference being that fighters can use the extra flexibility inherent in having extra feats to become as good with skills as a rogue.
