Oh this is where the title goes?
OK, that is not at all what I meant, I'm sorry if it came across that way.Moral of the story. Don't dig in after discounting someone else's suggestion with a criticism that applies just as easily to yours.
Your suggestion makes sense, but it is true that there is no fixed bonus crit damage you can add that makes the two weapons balanced for all ACs. It is also true that if you make the base damage balanced, then it will be balanced also when crits are included. You could instead decide to make them balanced with crits for some nominal AC target, I don't think there is anything wrong with that idea. It is just not how I took your question.
