I could totally see this being a thing.
I know that I enjoyed factions while I used to play them, BUT I came and stayed on this server because I knew what I built wasn't going to be wrecked.
Since a main focus on this server is the beauty of the towns, factions would be a whole new thing since people are having their factions constantly being destroyed and re-built. It would attract a whole new audience, so that would be fun, since this server is relatively small in average players online.
I think this should happen. It would be something new and fun!
