One thing I'd really like seeing in coming patches is that crown authority will be limited by one's succession laws. Elective only allowing low crown authority or medium at most due to it's essentially decentralized manner. Gavelkind as well should have an upper limit due to its tendency to splinter power bases. Only primo and perhaps seniority should allow for absolute which should be nigh on impossible to maintain in larger realms anyway though a small centralized one should have this as a way to compete.
