It might shock the top kingdoms, but the largest player base, the casual players, don't care about competing with the top kingdoms. If anything they want to be left alone and not be farmed (http://forums.joltonline.com/showthr...-This-Strategy). They just want to play the game in their own way, and fight with opponents that are their equals.
As I said again and again, the devs should take care that kingdoms stay filled. At the same time, having kd's filled with fewer players than the current 25 creates a more targets. There simply aren't enough players to fill 25 player kingdoms. The far majority already plays in < 20 player kingdoms. What's wrong with making 20 the norm, and fill those 20 instead of sticking to the 25 norm?! reducing size to 20 (5 per 100) creates 25% more kingdoms then there would be with 25 (4 per 100, 4 + 25% = 5).
For all i care it'll be optional to accept a 20 player limit, choosen by the monarch at end of age. The only drawback will be that a kingdom that doesn't accept the limit will not be able to attack into a kingdom that did accept. (And yes, I know this will feed the top kd's cry "you don't us to be able to compete", but then, top kd's can still choose to accept the 20 player limit ;))
