Yes, Bai used a Bai archive, again, I never disputed that nor did I blame her clan, I used a specific problem she had to make a point regardless of that problem's sources. I ever claimed that Ducal archives are a huge advantage because it allows people to circumsvent the problem I raised.
I never said "we shouldn't act like the other houses because other houses are wrong" I said "we shouldn't act like a house that pidgeonholes because here's some examples of characters that got dunked due to pidgeonholing, regardless of the why of that pidgeonholing, we shouldn't act in such a way that the chances of that happening to Biyu increase." I then argued that most houses pidgeonhole due to neccessity (well, that was more
@veekie than me, but I agree with him) and/or calcified thinking. The ducals being stronger explicitly due to variety supports my actual argument while Meizhen being pidgeonholed for reasons other than her clan leaves it untouched.
And we do have a clue, because Meizhen consistently places above Liling in the ratings. Also, their first duel resulted in more loss to Meizhen, so the upset was relatively big.
