don't know for sure about the whole Priest/Imam thing, I never got up to the level you can get them at with anyone but Abbasid, Ayyubid and Ghazni, still, I don't really see the need for them, since religious unrest in BC isn't that severe, and no fresh Imam has enough piety to call Jihad anyway (I've never seen one recruited with more than 1 or 2 piety, and you need at least 5 to call a Jihad. I think piety gain has been sharply decreased in BC, so religious agents gain piety very slowly).
