But with less nations, the targets get plumper and less numerous. This would let those darn WW have less big nations because the large players would all join one, I assume, and then the weaker players like me would be stuck with either joining a nation and never becoming a council member of getting another one and being by ourselves to fend off the big bad warriors. This idea would also shed down the number of NPC countries and therefore allowing nation changes to be faster even though the players, or at least most of them, agree that something should be harder about changing nations (joining or leaving is the question).
The king seat is important because you get more votes than dukes and have a veto in case the vote isn't going to plan. It also helps with diplomacy and authority within the nation as the King is the highest rank and should be able to shed some light on problems with lower-ranking members
