Once again, its not an issue of human realms not trying or acting together. The three northern realms were able to coordinate and march over a weeks worth of travel, have more CS and get wiped by one overpowered unit. Other realms that wanted the help could not because they have giant waves of rogues just taking over regions and not stopping. Playing the whole "oh its finally clear to retake this region that we need so we don't starve" game over and over isn't fun after we've been doing it for about a year now.
