A simple trading system could not exist in this game. It would just "break" it. You'd have players running around with weapons and armor achievable only through ranking up, raids, and more. However, a trading system could still exist nonetheless... Hence here's my solution that will never be implemented. You can only trade items between fireteam members that are present during the activity that resulted in the item being dropped. Simple. We do the raid. I get my 5th vex mythoclast and you got the helmet I needed... Boom trade. We both were there. I can't trade it to my friend who was not in the raid with me. For raids - loot items from the Templar can be traded with loot items from atheon if both members were present in the same fireteam for both parts. Um to make the system work even better, as soon as you leave the activity to go to orbit and then to another activity- no trading can occur. To top it off, if at any point a member leaves the fireteam the items can no longer be traded as well. Only problem I see here is random disconnects but eh... Deal with it lol. Anyways - thoughts?
