I agree, trading is silly in a game where everyone gets the same gear anyway. Now if there was some kind of crafting or something where each person had to specialize in one specific area then trading would be warranted. Or if the loot system were like Borderlands where you will never see the same weapon dropped twice then trading would once again be justified. Destiny doesn't need a trading system, it just needs a better loot distribution system where there isn't a disparity in luck amongst people who have played the same amount of time.
