You know, since they've said there will be one hell of a difference between peasant levies and noble armies in CK3 I wonder if they could implement a pop system, too - nothing too fancy, just something based on Adalberon's tripartite division, to keep with the medieval theme of the game; the laboratores are upset? Higher risk of peasant revolt. The bellatores are upset? Higher risk of court intrigue. The oratores are upset? The Pope is going to excommunicate your ass for sure.
