In ck2 after iron century update there was Mardavij dynasty which I loved to play (as zoroastrian it was good feeling to save Iran) I wonder similar events would go to zoroastrianism in ck3, I would love it to get more action and events about reconquering Iran, I would love to see you could restore zoroastrianism just like paganism in ck2, selecting doctrines, but this time there should be presets and those presets could not be changed because of historical reasons such as only presets being restoring zoroastrianism with Mithraism, Manicheism or classical zoroastrianism.
