Got a item you don't want but cant sell due to it being bound? Vendors not taking your cosmetics? Fellow knights not buying your items? Well then there's only one thing to do! Destroy the item! Costume you can't get rid of? Destroyed. Weapon you never use? Destroyed. Accessory you'll never use? Destroyed!
Plain and simple. Why I wan't this update? 1 word. Bound costumes. If you can't get rid of it anyways, but you don't want it, what damage will it do getting rid of it for good?
Something is better than nothing.
