I've never seen the AI reform a pagan religion. My first few games were in Vanilla, but lately I've played with all the DLC except WoL, HL or Conclave. I've also played a few games from each start date. Does anyone have any idea why? Do some DLC's make reformations more or less common?
I found old posts complaining AI reformation is too common. My games always end up with Catholic, Sunni (and to a lesser extent) Hindu dominating the map, with everything else pretty much gone or well on the way out. It's boring and predictable and I'd enjoy the variety or challenge that reformation would bring. It would be great if minor religions or heresies would occasionally do well, too.
Thanks
There are two main reasons. Old complaint towards reformation is not valid anymore because the situation has changed (mostly map expansion with farther away holy sites for tengri which was the most common offender).
- moral authority: it's hard to pull off enough moral authority with just 3 holy sites and overall the AI doesn't look enclined to actually go after holy sites to reform (it just conquer them randomly and press the button when starts align). Also unlike Germanic, other pagans barely raid (looting churches increase MA if memory serves right), and unlike the player the AI won't actively press county conquests, or build churches to get enough MA to reform when all other criteria are met. 750 piety is quite tough too if you're not pushing for it.
- passivity: defensive pagans are coded to be less aggressive and to not fabricate claims, so they conquer less and barely ever form unified realms required to reform. Also the AI mostly goes after de jure kingdoms with wants to be king ambition and then doesn't expand much besides subjugation which is restricted once per ruler. Think of slavic for exemple, if they only have slavic neighbours, they can only subjugate once per lifetime and since they don't fabricate, they will never get other CB to press.
I personnaly moded down moral authority and piety requirements, removed the aggressiveness penalty and regularly see Germanic reform. I'm yet to see other pagans reform but at least I've come up to see united West Africans pushing out of Ghana or Carpathia strong enough to stand its ground for a while. Playing higher difficulty helps too as the AI gets more money (thus is more likely to create titles to keep unified realms).
