Ah yes, your right, it indeed does change the faction and such. It is just I like a lot of the Heresy feature, but as you reasoned it is needed cut out for more sandboxxy campaign. But indeed would be cool if Pope-mechanics would be re-intoduced then, and they kinda make sense.
Rest sounds good to me, only thing I'm not sure is Orcs buff, they can be very OP with AI. They were nerfed back in days, and the whole main reason Border-Princes got implemented to the game, was to slow down Orcs steam-rolling Empire.
