If you mean that selling Saviis is pointless: the percentage of Saviis that eventually get sold is closer to 20-25%.
If you mean that too many Saviis are created: I say the more Saviis there are, the more crappy Saviis there will be, which makes the awesome Saviis that much better. (Not to mention it keeps the app popular.)
If you mean that too many Saviis are put up for auction, you're absolutely right. It's not that people don't bid, but really that a lot of Saviis aren't even close to worth bidding on.
I don't really care if there are "too many saviis" it doesn't affect me.. it does get irritating when people expect you to bid on a "lame" savii, because they don't want it anymore.. just delete it?
