Meanwhile, bind-on-equip items will still need to be equipped by one of your characters in order to unlock the appearance, so that much hasn’t changed. This should prevent situations where players trade appearance items around for a fee in order to unlock appearances on multiple characters, so these are either sensible and positive changes (if you weren’t engaged in that anyway) or really killing something you did in the game (if you used to do that and now you’re going to be stuck unable to do so). Good luck to the appearance hunters in the game!
