Timed live random public events that put the Tower and other hub areas at risk. Guardians that are online at the time have to ward off waves of enemies climbing into the Tower, attacking citizens, factions. A notification sent from the app can alert guardians who are offline to log in during the 15 minute or so event. Guardians could also text or call their friends to log in to help. Based on number of Guardians and your performance, you get end game or better rewards. You also see damage to the tower or certain areas like the vault or ship dock are damaged for a few hours if the guardians aren't successful in pushing back the attack in time. Or the entire Tower could become unavailable for a period of time so you have to go to the reef or somewhere else to access the vault or get bounties. Also, open up the damn city to be explored and also be an area for patrol and public events. With games like assassins creed and witcher, why are there so many invisible boundaries in destiny?? Why does it also feel empty in the tower and "open world" environments?" Feels inexcusable. #Feedback
