love johnny smiths idea !TBH I think maybe do something slightly different on server 3 so people can choose there preferences because if they are both identical (server 1+3) then i think people will just choose the one with more players as that's what allot of people do for some reason, just see which one is busier and choose that one. I think one of the servers (say 3) could also be used as a slight beta server to test new suggestions and ad dons that have been posted on the forum's. That way if something doesn't work properly it want effect the majority of the player and they will have 2 other servers to choose from.
Thanks for reading, Hope i made sense
