Tower/reef is pretty boring right? What if at some point in time while people are in the tower or reef. The darkness attempts to attack it. Have a siege clock ( siege imminent- x amount of time till it starts) have it happen like every 4hrs. 6x a day Max people allowed in tower is 16. 16 guardians. Broken into teams of 4. Defend 4 different areas. Confluxes or whatever. Anyone who wants to do it goes to a certain area in the tower And is teleported to the siege area. Cutscenes shows the enemies coming And begin! Get some kinda legendary award etheric light. Nothing crazy. Just fun Make it not to hard. Just something to do. Instead of standing around. Each siege can be different level requirements Basically a more organized public event
