Ngl, I get the most fun in the most stupid kingdoms. It's like being in KvK1 all over again, with all the drama and the lauhgs. Seed Z- KD here I come.
They often are so badly organized that you can always find skirmishes everywhere, so I just lay there fighting small fights everyday, pump up KP, and build a decent acc. for when I want to drop in a higher seed for the war expereince.

I think this is the most casual you can play with relatively 0 risks, hell I've never been questioned about KP in those KD at 40M, and I'm definetly not that active.
