I don't think so, we have like 6 clans all trying to cramp into the North right now... Needs more fiefs above that river in my opinion.
Factions which don't have the troops/players to support the fiefs (if they were attacked) that they currently own on NA-
BIRD CLAN
LL
Order of Saints
"Mangos Mexican Farm"
"Placeholder"
"Ganners Wild and Crazy Love Shack of Debauchery"
Free Peasants of Fisdnar
The Super Friends
Not to mention the fact that not even all AI villages have been taken yet and that I have probably missed out a few more factions from that list. Also I am aware obviously some of these are just friends of big factions so you would get their ire by attacking them but honestly most of them are not.
I don't have anything against these factions but if the map was the right size, real sized clans would be attacking these guys for fiefs instead of not caring because there are more than enough to go around.
