I suppose the main issue is a kingdom has a good age but then they cannot maintain it the following age and to be fair its also down to the lack of competition. If you only fight ghettos all age then you lose your edge.
for me FS is the current standard setters because they've done it age in age out and constantly have good ages.
there are kingdoms who as celien said "got great potential" but they have to do it for more than a few ages lol.
the same can be said for the top 10 land charts - there is not enough top class competition now - I mean EJ and Vengeance are almost top 10 land kingdoms lol. Kingdoms dont even have to run cows now lol.
