All council members are only as powerfull as they are liked by the realm.
(...)
As I pointed at many times before, depriving formal titles from real power deprives game of exciting actions. When all title holders can be removed by more than one means, they should have power (and, absurdly, the only title which holds realm power -non-council title - is untouchable), so the balance would exist between their power and power of those who dislike them. Quarrels about power would create much of internal political frictions and indirectly create foreign frictions too in many ways I will describe later.
Currently the necessity that council needs to be liked by most of realm create some sort of liberal democracy that has almost nothing to do with medieval atmosphere - fine people doing fine thing, all respect each other, ideal for real life, terrible for the game.
Even the only example of "noble democracy" that of medieval England - balance was fragile all the time, power abuses attempts frequent. Once harmony was reached, middle age was already over... Without power there are no abuses, strong characters, strong stories, nothing.
With mechanics which forces ruler to be some sort "prime minister of minority government" the most frequently we have two scenarios:
1- everybody does his own business, no any real cohesion within realm exist. Besides putting gold in pockets almost nothing happens as no-one can move something to happen
2- over time council, or ruler, created reign of very submissive followers. This mostly works in some very old realms who had luck to never be exposed to some more serious test of strength. Apathy is dominant feeling. Leaders will take care to never disturb customary submissiveness by any new initiative, being fully aware that they cannot gain absolutely nothing, but they will likely lose everything but introducing change in fragile balance of their informal power.
All described i caused by game mechanics. It is like mechanics wants so impose consensus as the only way of realm society's functioning. Together with the mention fact that success in achieving such consensus means boring idyll, it also derogates many founding stones of medieval values - as it was nicely described in some Wiki articles, nobles lived and died for formal title, that meant everything for them, that way their main objective in life and motive which moved things forward. How can that work if titles are apparently empty...
