I mean, I did just make a suggestion that'd solve a good percentage of the problems. Toss in a dragon wild shape style note about how you can't gain casting even through Ex special qualities and you solve one of the bigger other problems. I obviously still don't know all the possibilities within that set, because I don't know all extraordinary special qualities everywhere, but the problem space is a lot more limited. You can still attack folks from the ethereal plane, but you can't do all that other stuff I was talking about. Still probably land around tier two.
