I think there should a bar for each planet with one side being one enemy type and the other enemy on the opposite end (I will use earth as an example) Fallen is on the left while Hive are on the right They each start out in a specified region of the cosmosdrome and advance on each other We can check the app... Look at the bar and see the cosmos time is predominantly fallen today or something We can even further this by being able to click on the bar and bring up a map of the cosmodrome highlighting the positions of the hive and fallen There could also be another type of public event where there is a planned give invasion of a fallen headquarters We could go and influence the outcome of the event and get points for displacing or eliminating a fallen/hive headquarters Headquarters could also be like a new type of mission kind of like a cross between a strike/public event/raid Whoever was in power can influence enemy placement and public events (if hive were in power the sword of crota events would start spawning again) which would give us a reason to influence power struggles
