No actually what I said was that the system was mocking players who wanted themed characters by forcing them to either break theme or be gimped in numerous encounters. This feat does not give tremendous cosmic power, it fixes a flaw that naturally accompanies specialization.
So, where is the feat that fixes the flaw of Resist Slashing damage?
Is the fighter who loves his greatsword gimped? I can imagine a fighter who hates other types of weapons, just as easily as I can imagine a fire dragon sorcerer who loves fire.
