I can see why GoF would be broken on aps classes. It would piss a lot of people off to suggest, but I would recommend removing it and replacing it with something else that is useful for sins. Putting GoF on claws really wouldn't help the problem; it would just cause people to make an exodus to aps Barbs and then there will be another thread about how people can't beat GoF aps Barbs. The whole thing would be going in circles.
