In a way to prevent this whole one clan holding 30 cities leaving all the smaller clans with nothing, what if we changed city nodes so that they regenerated based on players bound to the city with a current subscription running? To further add to that, what if they regenerated once a day in the future siege window for each city and was publicly available on the world map? This would provide a single point of time of PVP for each city. It may promote clans to have a main city to get all of their bonus ores from a certain mine and to help defend their mine as a group. Of course these same principals would apply to all city nodes. Just a quick thought I had.
