I like the event to break the monotony of grinding during the Anniversary and CV event. Activity after these events really fall down low, iirc there is one Friday night where i only see 3 rooms in Nebraska. I think some people are on break after the events. Playing NF continuously for weeks and you'll get sick of looking at it in the following month.
Although this event will propel people with relatively low skill (200% exp!!), it will increase population for a while.
Well, you can't have everything.
P.S I cant wait for the new game engine
