I hope you don’t mean every piece of equipment we pick up is bound. I literally farm, sell stones and buy equipment on AH because I don’t trust my luck in upgrade System.
I assume you just mean things that are bind now will just become account bound. This leads me to assume you are added a shared bank that all characters on 1 account have access to, correct?
With the upgrade system change, you no longer have a reason to not trust the upgrading thus you no longer need to buy equipment from the AH.
There will be a storage made for the account.
