Having played M2 a bit and followed WoS, I'm curious how the Chancellor or the Diet will deal with the Pope. WoS with RTR platinum didn't have SPQR edicts but the HRE will have to cope with Papal "suggestions" and the possibility of excommunication. Considering the expansionistic bent of WoS this might pose some problems considering all its neighbors are Catholic (I believe). Also, I believe, the HRE begins the game with low papal standing. There is also the Council of Nobles with their own suggestions, though without the dire consequences for failure.

So will papal and council relation be left up to the Chancellor? Or will the Diet regulate relations with edicts? Will that be the same with Council of Nobles edicts? What would happen if a crusade is called? Could a Duke decide to embark on a crusade by himself with his own army, or would he need permission of the Emperor? If a player has a priest avatar would he direct the movement of the priest or would the Chancellor? Who decides which Cardinal to back in Papal elections?
