I don't understand the point of events which are split up in to multiple instances. It seems counterproductive to host a community wide event, and then split up the community on the day of the event.
>but muh lag! muh frames!
This game runs like shit and whether it's 40 people in an instance or 80, it will still lag like shit. I'd rather be with everyone in the instance and be able to hang out with my friends instead of being able to get 10 extra frames in an overflow instance where none of my friends are.
