So here is my idea! We could have public events at the tower that either the hive, vex, fallen, cabal, or taken could attack and we would have to defend the tower. It would be like a VIP patrol but if they got to one part of the tower then it would end... but if the guardians of the tower could last, then it would drop great loot! They would not happen super often maybe 5 times a day and it would make public events more relevent in destiny! Please add more ideas in the description and bump for more people to see!
