I like it. Every now and then you can, as a large imperialisic nation, simply catch a string of bad luck and end up with a ruler that has terrible stats. Now, normalyl that means that your expansion sort of has to stop for a while, either htat or you lag behind on tech to continue your expansion. Fair enough - terrible King, maybe he just isn't good enough to manage to expand his dominion. But even an imbecile of an emperor that owns half the world could hire someone brilliant to help in these efforts. Gameplay wise that also helps a bit to further counter those potential times when you are arbitrarily limited from doing what you want for mana reasons. (The limit is still there, now it's just two steps higher, which I like).
