I Said no in the poll as I believe any open trading system would break the game but I thought maybe and just maybe it could be a super limited one. Such as trading the items on the reward screen only. IE you get a shotgun your buddy gets a pulse rifle from the same strike/game you can trade then and there only. This could improve things for a lot of people. As for materials I don't think so those should be purchasable or exchanged in some way with NPC venders
