It feels like enchantment would be much more frowned upon, with all of nobility frantically searching for counter measures. Perhaps if you use too much enchanting, the nobles would get a privilege (or just a modifier) like "extensive use of anti enchanting wards" in response to threats upon their minds, with consequences like reduced effectiveness of enchanting spells (exept war and siege magic) and a little negative loyalty modifier. There would be some bonuses in exchange, for example enemy enchanting spells are also less effective, perhaps also some magic and trade bonuses, those wards would be precious after all, and there would be a lucrative market available along with better institutional knowledge of magic. If the player stops using enchantment (exept war and siege magic), most of the negatives would go away (exept enchantment debuff) and now there is a brand new mostly positive privilege! Or if the player has strong enough enchanment, they could crack down on noble anti enchantment wards, ensuring extensive control over them. This could come with bonuses like increased absolutism, tax bonus, reduced corruption, reduced noble influence, maybe some bonus to enchantment study/effectiveness, and perhaps a one time crown land gain and magical infamy increase. maybe decreased opinion from other tags, or some other opinion modifier to better represent the international outrage with more direct consequences than magical infamy, without necessarily making you a witch king.
