I wouldn't mind title swaps for priest characters only though, like Count --> Bishop, Margrave --> Prince-Bishop, Duke --> Archbishop
It would be hard to come up with good titles but I must say I agree it feels weird calling priests a Count, I don't know why it does so much, but it does. Even in a roleplay I saw recently, when he was in conversation he said, ""Lord, erm, Eminence Constantine," Rynn fumbled, not quite knowing how to address the man"
