We can assume Big Mom was even using AdCoC, but "invisible", or offpanel, since author is pretty limited when fights.

Kaido, unlike Meme and Luffy, can't use AdCoA (at least that's what we've seen from him) so Law tanking it–even with pis–is still acceptable for "average" fans, but Meme has AdCoA too, there's no explanation to that. How can Kid and Law tank that? They can't. That's why Meme didn't use it, and that's why 80% of the fight is off screend. That's how Oda writes now, if he can't explain then he will simply avoid it, off screend it, avoid all the questions. The stupid fans will find an excuse themselves, endlessly debate about something that author didn't even bother to show.
