They need to open Nexus on GST days. Giving the 1st and 2nd place guilds a VIP room like the old 1k VIP rooms for tower guilds. They could have some basic items for sale at a cheap price in which they could invite their friends. The same items would be sold outside the VIP rooms, but at a higher price.
Will give guilds a place to celebrate and keep the player count high the whole day.
Way off-topic, but what the heck
