No trading. Destroys the concept of [b]Character Investment[/b]. People are in the hurry to achieve the best gear after one week of the game being out. Destiny already allows players to pick up gear for other classes, and then able to be stored inside a bank/vault. Earning gear is much more rewarding than buying it offline from someone on Ebay. Spend the time to play, have the more opportunities to grow your character/characters and gain better gear. Otherwise the whole peer to peer trading system will break everything that Bungie has stood on. [b]Character Investment[/b].
