I feel like we should have a loyalty mechanic

Right now in the game if you have a powerful vassal with a neutral to negative opinion of you they are certain to rebel at some point if you don’t bribe them, even vassals with very high opinion will rebel if crown authority is too high.

i have no problem with this but i feel the game is lacking actual loyal characters that would not easily rebel against their liege for personal reasons. This can also be tied to the legitimacy mechanic. A character with a loyal personality archetype would not rebel easily even when having a negative opinion of the king because he respects either what the king represents, or what the dynasty represents.

Think of characters like Barristan Selmy who would serve an horrible king because they are extremely loyal.

Though i feel a loyalty mechanic would work a little bit better in an administrative gov type, with bureaucrats that were loyal to the state even when they did not personally like the ruler, i can think of a few examples in imperial china.
