I think that Chayots should be unwishable as they are too expensive, but other nationals shouldn't. It just makes a nation way too powerful in the endgame if it has summons like Grigori which nobody else has access to.
So if Seraph is made unwishable, the races that have such endgame summons will have a terrific advantage which I don't think is correct. Somebody said recently (IIRC, it was thejeff) that late game should be balanced and every nation should have equal or nearly equal late-game abilities. Yes, it is boring, yes, the strategies are similar, but it is balancing and balance is a VERY important part of this game as well as any other one.
