Bagspace, eh. Bankspace, thats what I need! That'd clear my bags aswell.
Heh, I have tons and tons of transmog stuff. I'm on 60+ weapons alone >.>
They should let us destroy transmog gear and allow us to keep the skins in some menu on the vendor or something.
Ye, make some kind of database on character level that stores all skins from all equipment you ever had. Then redo the transmog UI so you can choose from a dropdown menu.
Don't think this can be retro-active, but this idea is the best I can come up with.
