I've wondered this for a while, when you tell a priest to preach and get the message "Preaching won't increase dominion any higher in this province" does the preaching force a dominion raise check in another province or is it a waste?
Yeah, I kinda thought that but its the human condition to dream. Maybe in dominions 4 you could Wish for dominion to spread outside of the province your priest is in if the current province is full.
