Most people say that having such a thing in the game would break it. How? If you have a buddy you want to go on a raid with you, and you have a piece of armor you're not going to use. But your buddy needs just one more piece of gear to compete on a higher level. Why can't I trade it to him for something I need or want? For a game that's supposed to be about playing with your friends, it's seems like it takes every opportunity to hinder any kind of team work.
