The more my empire grows, the less power I seem to have. If there are any votes like making peace or granting fiefs, my council makes very bad decisions, but if I try to hinder them from ruining my plans, it costs me easily 400 influence and the more lords join my faction, the more it will cost me until eventually I have no voice against the council anymore and they will make all decisions, which kinda ruins the whole idea of having your own kingdom. If I conquer a big city, there is not even the option to grand it to myself and I have to give it to one of my useless lords, since I already have 2 cities, which is not enough to cover my expenses from all the trebute I have to pay now thanks to my councils decisions.. I dont know if its the same for other factions, since I only played as part of the empire culture so far, but for empire its certainly a big problem.
