"Typical" players will rarely be a problem, but one "extreme" player in a normal game, taking advantage of the rules as pointed out here, sets the power level for the game, not his normal buddies.
So everything should be balanced against the various overpowered builds? That's completely unworkable. Feral and Mineral warrior are dramatically overpowered and shouldn't be allowed in a campaign at their LA, if at all, any more than you should allow the worst of the divine metamagic cheese unrestricted.

Case-by-case judging is an absolute neccessity for a competent DM.
