Everybody Knows by now that this game need a trading system. Im not saying Bungie should put extra work into that or anything but there might be a different way on doing this. The reason why Bungie can't make a regular trading system is because they do not want players to glitch it and duplicate what there trading, but if bungie can make a system where you can turn in a exotic for a different random exotic or a legendary for a different legendary then here how they can do it. Players can use the exotic shards and commendations for tickets in the randomizer. Xur would be the one who radomizes a exotic but he only does it 1 time per week after that you are stuck with the random exotic until next week. For the legendaries, you have to go to the vangaurd or crucible quartermasters to use their randomizer. It can only be used 1 time per day. this could also work for the factions but you must have their weapons in order to do it. That is my opinion and idea. Hopefully Bungie can get an idea from this, if not then Bungie has a better plan for the future.
