How would you like to be able to trade? Say that you finally saved up for that exotic engram from Xur but what you get is not for you Warlock. Its for a titan. Hey! Your friend is a titan! And hes got an item that you want! imagine that you can trade with your pal and youd both be happy. (Except that you dont have that exotic anymore) But at least it still made someone happy. And yes, the gambling aspect is fun and you are never sure if youll actually get that Warlock chest piece or not. But why not just give it to your friend if you dont really plan on creating a Titan just to put that chest to use. In the end, everybody will be happier. We can finally trade, and no more complaining.
