My point is that the powercreep is non-existent. Shanks is just Oda's golden boy. Kaido will at least still look very strong in 100 chapters.
I doubt it
Dragon, Imu and Mihawk are about to look completely more broken than Kaido
and Blackbeard too, with given time
Luffy, Zoro and Sanji will all have to grow to face the challenge too
and there are still the Admirals left
so there's gonna be a bunch of characters looking better than Kaido and Big Mom before this series ends
the power only grows from here
