At least for the first 6 original east and west coast servers. Servers 1 and 2 both have 6 groups active in their local Great Ninja War. All the rest have mainly 2, some 1 and a couple with 3 (lucky them at least they get 2 rounds). The populations on servers 3 - 12 are starting to dwindle and the communities are suffering for it.

It's time to either merge those 6 servers together or to move them into the much larger cluster of servers from servers 13/14+
