This could be a really great mod, and as it stands, I love playing it. But there are too many factors than make it an unenjoyable experience far more often than not.
Admins are rarely on the server and once that is known, players and factions severely abuse the rules. For example, I was just playing on the NA server where the largest faction at the time decided to go from fort to fort attacking everyone without warning and without declaring war. They simply killed who they wanted, when they wanted, and they got away with it because no admins were present and they outnumbered anyone who could potentially stop them.
When rules are followed/enforced, this is an incredibly enjoyable mod. Unfortunately, the lack of admin presence severely hinders the mod's potential.
A somewhat less often occurrence, but an annoyance nonetheless, is that the servers crash fairly often. I don't know if they are designed to shut down at a certain time or if they truly are just that bad, but it creates a frustrating experience for players who spend a great deal of time making money and raising a faction when the server randomly quits.
As I said, I love the idea behind this mod and I do find it enjoyable when everything works as it should, but these issues really should be addressed.
