From my perspective, MattKan is being the prick here. He had a special list of rules and guidelines just for his own enjoyment, one being you could only declare war when he was online; which kind of ruins the purpose of "kingdoms."

Having an OP as a kingdom owner is a horrible idea, since they have a huge unfair advantage with access to item spawning and other shenanigans. Even if they don't use stuff like that, players would still feel discouraged.
