The skywatch public event is sometimes impossible to do, especially with Urzok coming in, so I have an idea to change the event. The event should just be the enemy moving against each other. They could have varying objectives for it such as "kill 20 hive or fallen majors" or get 15 kills with your super". If this is achieved by one of the people in the event then it could trigger Urzok to come in, who will be the target to kill in order to complete the event.
