Perma-bind equipment.
The idea is, players sooner or later will have what they desire and want. Due to this, they will not want to trade, or "sell" to vendor that particular item.
This idea is to perm bind a particular item say for 100 CE, to that Character, it cannot be sold nor traded, unbind. Once bound for good, it cannot get rid of.
The purpose behind this is also to help protect yourself against hackers who do get to your account. They cannot sell the weapon you created to vendor or trade it even if they use your CE to do "try" to do it. In this case, you'll at least keep the weapon you have. In this case you should be able to still have Punch. "Maybe" upgrade it, thou still have the bound to that particular person.
I think ppl would feel more secure and safe with this particular option. This could be an add-on to Punch, as he deals with tickets to enhance, etc.
Thank you for reading this.

Then OOO will be swamped by responses from morons who perma bond stuff they regretted, or they changed their mind. Then they whine about OOO settiing up a cheap paywall. And so on.
