Crusades/jihads and religions reworked.
WHY and HOW?
Crusading feature is VERY exploited by player. And its boring to see doom stacks on one city going. Thats not how crusades realisticly functions. Also, AI cant handle it properly. He is dying, fighting to survive, and then sudenly he send last stacks on crusade...And faction die...Also historicly speaking its unrealistick too see scotland, norway, aragon going to palestine while they have other problems in they countires..Pope even forbiden spanish iberia nations to go in holy lands..BECAUSE they had they own crusades against almohads/almoravids. So crusades are already portrayed in holy land, faction crusader states.
But then how to remove it, what to do with catholic faction? DO similiar to medieval 2 kingdoms britania, or also europa barbarorum 2 mod.. there is 10 or even 11 religion slots... Divide it into cultures or something like that.. that will make even deeper campaign map, because for example if u capture italia with spanish faction, u will have many unrests and rebelions.
For example, there is shia muslims, sunni muslims, eastern catholics, western catholics, spanish catholics, nothern catholics, balkan orthodox, rus orthodox, pagans...etc..
