And that's one of the points I have about Kaido and his tankiness. Big future enemies of Luffy won't stay down and will keep on fighting after receiving hits and hits from a stronger version of the Luffy that will ultimately put down Kaido.
Man, don't hate him for being that kinda smartass, but I don't see that happening, honestly.
You could have said the same about Boundman, which is still probably able to knock out everyone bar BM and Kaido within 2minutes if he connects, but Oda still found his ways around it:
1. Cracker creating an near endless army of Buiscuit soldiers with instant regeneration
2. Katakuri having not only FS, but a logia like body deforming tech, which lets him make attacks slip through.
Just take the admirals for example:
Fujitora- Gravity so strong, you are barely able to go against it.
Aokiji - Casting ice walls out of the ground for blocking stuff
Kizaru - Basically just blitzing around and dodging
Akainu - I dunno, perhaps Katakuri 2.0
And that's just me from out of my head, who's is not even 1/20 as creative as Oda.
But yeah, overall I still feel you guys, can't say, that for the moment it does not dehype that ability a little
