Anyone else feels Crown Authority is extremely easy to increase in this game? Decentralized realms should really not be able to achieve anything closer to High Crown Authority until the endgame (it'd be more historical too)!
Perphaps it shouldn't be a three-step process, and maybe you would require to have certain (very large) amount of prestige/piety and control certain percentage of the realm directly before each step. I'm thinking something more like the process to centralize the HRE in EU3. As it is now, everyone has Absolute Crown Authority within 100 years.
Oh, can anybody explain to me the logic of needing High Crown Authority to change certain succession laws? Since the description for Low Crown Authority states the vassals rule their lands like petty kingdoms, you'd think that means they can also change their own sucession laws freely.
