I would support separating EU/NA completely because it evens the playing field as far as ping is concerned, and more battles will be fought during prime hours for both sides.
Also, I think having less clans dominating would prompt new/small clans to rise up and at least take a town, maybe gain more members, and grow. Right now the map is EXTREMELY noob/clan-unassociated unfriendly. That might be ok for a game with a 10,000+ player base, but not for cRPG. I would like to see this mod grow if possible, but between repair costs and large clan takeovers, it won't likely happen.
