I hate intrigue kids
Always when I get kids with intrigue education they end up killing everyone, getting caught, banging everyone especially their siblings, getting caught, having every STD, having every sin, having a -90 opinion from everyone and when I finally die they usually end up getting in a hundred vassal wars because of that.
Stewardship heirs usually are rich and have stable empires, and diplomacy heirs keep vassals in check and have lots of kids, martial kids can atleast win every battle guaranteed, learning kids get new techs super fast, but I can't get the benefits of an intrigue heir because they are too busy making enemies with the Catholic Church and being incestuous.
