At this point I don't really care about whether it's accurate or makes sense, I have played a couple of big campaigns after conclave dropped and have left the game alone since. The game is fun to play and makes sense as long as you're weak in terms of size and or council power, but the moment you are both large and have the realm completely under control, you have nothing to do. Depending on your religion/government you will have literally nothing to do unless you want to murder people just for spite's purposes. You sit around on your hands desperately hoping the Caliph declares a jihad so you can actually do something.
All I really want is for the defensive pacts to be optional without disabling achievements, because at this point, the moment Reaper's Due drops I'll never play for achievements ever again.
