If it will be allowed there should be certain hats that cannot be traded. Guild hats, Event hats and RPS hats. Make more body and head shops. That way people still buy stuff. If there's a head or body someone likes there and they don't want to pay 10k-20k for a custom; they will buy it. Make them like 3.5k-8.5k, you could still use packs for that. Just be sure there's a lot of them and they're actually good.
