I think I have a trading solution. Since Bungie doesn't want us trading with each other. What if there was a vendor in the tower that came the first weekend of every month. He would have about 15 to 20 exotic and hard to find items. To trade you must have two of the same item in your inventory. So let's say he had Thorn. I have two Thunderlords in my inventory. I could trade one in for Thorn. This would limit trading but also help us get new items if we have multiples of the same exotics.
