There should be a quest line at some point where we take a fireteam into the old destroyed tower and managed to aquire an exotic of our choice from D1. Give us a list of all the old exotic armor and weapons and allow us to pick 1 item to aquire from the destroyed tower expedition. Items could range from exotic nightstalker cloak to exotic storm caller bond to the exotic swords or the Thorn. And Sleeper Simulant and Pocket Infinity should make a comeback since we have a warmind DLC.
