Actually my concern with trading is hackers. If trading is enabled its an invitation for them to go around other player accounts and grab the hard earned items that we prize so much. Sure, the RNG is a pain.. I also got screwed by Xur Exotic Helmet Engram. I play Warlock, and was looking for an helmet.. got a cool one for the Hunter. I can't really put myself to level a 2nd character right now, but I will have the item when I find the heart to go through that process again. In the meantime I even got a legendary armor for the Hunter from an Engram.
