I've thought the same thing for months and I think its a great idea.. It will have its faults though. If you do that then you'll just have these good at hard people who don't play the game anymore practically give their exotics and legendary away. Maybe it could go on a point system. Every item I'm the game is worth so many points and in order to trade your item points and theirs have to he even. Just a thought but it could work if you could fix all the bugs in it
