Seems like good solution for keeping servers last longer. Although at first lunari for emigrations seems like unreachable for many players, it will keep it under control so that you dont have full server of yellows in 24h for example...
King system also seems good cause there is limited spots and im sure in combination with emigration it will encourage kingdoms with too much members to emigrate in dead kingdoms to be kings or men with position.
Well thought guys, in theory works great but we shall see

One thing i would change thoe, its not fair to have prince but not princess or king but no queen... is it so hard to make pop up window that asks you if your girl or boy?
