Yesterday I was completing bounties for vanguard reputation, and suddenly a rare drop is rewarded from turning in a bounty, a ship "The Fangs of Nyx" I believe is called. I was very happy because I've never win anything else but experience while turning in a bounty, then I go to earth to complete some other bounties and I get the exact same item from a chest. So, I thought that it would be nice if I could mail this to a friend, imo Destiny needs a mailing system that restricts legendaries and exotics, that way players could share some items between friends. I understand this could do some harm to game balance, so another option would be an exchange system, sort off like gambling, you give an item to a NPC that has a random chance to give you another item of the same tier or above or a little glimmer if you're unlucky. Sorry for my bad English, I'm working on it.
