I don't think you should call them "Nation Leaders"

I think you should call them "National MVPs".

According to your description about the game, the "Nation Leaders" have no relation to leadership and decision making.

 

Nope, that has no effect on you either. I'm guess it's just the minecraft updates affecting your FPS.

 

Might be.

 

I just glanced over this, but it seems like a pretty cool idea. I'd love to see some more pvp based minigames added as an extra part of the server!
