The smaller realms with fewer players will now always have more national power than the kingdoms with more cities and with more players because they will have more targets to attack.
Now being a small kingdom is positive. You can attack many players from other realms with resources, they will only steal 20% of the resources, you can repair 50% of the wall in 12 hours and it will take 16 hours to heal all the troops.
Easy to say that when you are on the other side, Neuro. I have alts on both purple and blue and i guarantee you they have 3 times more rss from Towers than my main account on Green.
