Destiny doesn't essentially need trading. On the other hand I strongly agree with the article, trading common and uncommon items sounds like a great idea. Maybe with set limitations so that a young player can't trade a bad weapon for a good one. In the end I would say that trading in Destiny would be extremely cool, I for one honestly can't say I wouldn't like to see it. While I see where Bungie is coming from, I still strongly believe trading would be an awesome addition to this already fantastic game.
