The reason we are playing with the old guns is the newer ones are not nearly as good. Make better weapons that are better and more fun. The newer dlc weapons are seriously lacking in imagination and don't feel nearly as powerful. Not to mention they are not very fun to use. If they made better more interesting dlc weapons I would gladly give up my old ones but they seem to be too scared to make something that might be OP and thus all the newer legendary weapons feel bland.
