Are you not witnessing the same thing the rest of us are? Kaido and Big Mom are true Top Tiers. They are giggling with glee because things are starting to get "Fun" for them. Luffy, Zoro, Kid, Law, and Killer are giving it their all, and the two Yonko's are happy to just be having fun. All those attacks, and Kaido is clean. Big Mom doesn't even have a scratch. Kaido wouldn't even risk going into Dragon form against a real Top Tier, as indicative of his fight against Big Mom. Kaido just went hybrid, and the Worst Gen are about to get their shit rocked. Quote me on that.
