Yep, these are the two causes I was thinking of. Early Scientist, Merchant and Artist slots are most probably being (re)introduced in 0.9.4 and this will go a long way towards mixing it up a little. Number of religions seems to be a personal preference, which is why I hope to make it player customizable. I can make a setting in one of the xml files that the player can edit as they like but that's messy. I'd love to add a slider to the custom game setup screen but it's unfortunately unmoddable even with the SDK. However, what I might be able to do is to 'hijack' the Choose Religions option (which no longer does anything in HR), rename it "Fewer Religions" and provide an alternate, lower limit that still scales with mapsize. Each leader has their own settings/personality for this, independent of their traits. I've coded the Spiritual trait (Theocracy and Fundamentalism civics too) to get a bit madder than most when inquisitions happen but that's a completely separate mechanic.
