I would like to see more ranks. As more players join the spread of points will increase. By next year there will be 30 or 40 generals and probably 300-400 colonels. The point spread for colonels will eventually become a problem. There is a difference of 1,000 points, and only 200 points for captains. I would suggest the following.
Leitutenant colonel: 2,000-2,500 points
Colonel: 2,500-3,000
1 star General: 3,000-4,000
2 star General: 4,000-5,000
3 star General: 5,000 +
Also I do like the idea of a supreme rank, it could show the persons rank but then have something else superimposed on it, like a title: supreme commander or something. This would be for the player in first place.
