Personally i feel like trading should be in the destiny and there always should have been, except the only problem is that everyone is afraid of level 30's giving level 20's exotic weapons and armor. i have an idea of how this could not happen and trading still be in the game and kept balanced and fair. have weapons and gear only be able to trade with others of its sort (you can only trade rare items with rare items and purple with purple etc...) i feel this could add a certain umph to the game and have it not be overpowered and people giving each other items for free. i would love for this to be in the game whether it would be only in dlc or for everyone. i just want this idea to come to life and have it implemented into the game. let me know what you think and how well you think it would work out.
