Actually for leader person there are no need for LP and stats... my main stats is agi and const to survive... I just don't need them.
I have crafters, farmers, hunters, fighters... So when everything organized and all people busy you don't need to much time for all this. Of course you need few people to help you with this.
Also I think lot of citys system is wrong. One big city with mining forts or small colonys is best.
