office analogy is bad example, because back than, during medieval times, king could do all things you mentioned, without any consequencesRaising taxes too high, getting into expensive wars and infringing on the "rights" of the nobility was what caused lords to rebel. Telling someone to follow your army is not infringing on lord's rights.
An office analogy would be your boss sexually or physically assaulting you, embezzling money, or doing something that oversteps your rights as a worker. But beyond that, bosses can do a hell of a lot without their workers rebelling and calling for them to step down. Your boss can do unethical stuff like demand absurd amounts of overtime, but most people just sit back and take it because that kind of thing is actually expected of bosses. In a game setting he would lose relations, but not influence.
Medieval 2 total war, for all its faults, had a very good system for king characters called "authority" which was a measure of how loyal your lords were. You gained authority by defeating rebel armies and getting into battles with your king, and you lost it by losing battles. You barely had to think about this system beyond "use your king in battle", but it made a lot of sense and you could understand why a lord might feel like rebelling if his king was sitting around in the capital while he was out fighting.
joke aside, for minimum next 8 months, we won't see any new features except voting system, and maybe new quests, and it's a big maybe.
