So I can pay too many bentos to a VIP for an avi they won't use anyways. Or some people have alts that they got a super rare avatar in, and they can't put that on their main. (mostly the latter)
Have you seen any VIP use anything more than their: 1) best stat avi or 2) their 0/0 stat avi I see none putting on old hunt avi for nostalgic purposes even. I'm sure they'd sell some for bentos to get other trash with instead of hanging onto something that is even virtually cosmetic.
