Especially with the new patch, a way to remove items bound to a player is necessary. I would suggest a machine like the "Alchemy" to scrap bound items for crowns. I can see why high items are bound to players and don't think developers will make a way to unbound and keep items so provide a way to sell them back like minerals are sold. Otherwise items are going to just start piling up in players inventories with no way to remove them.
