Future Events Shanks will lose to Kid, only the new era matter

[Luffy is the mc]

depends on the movement, kid was standing still

And he could have still applied haki on his body. Zoro did that in milliseconds when King used Jackpot.
Kidd just has zero reaction speed.
We have also seen Katakuri change direction in the middle of an attack to hit Luffy.

So it was perfectly possible for Kidd to react to Shanks attack if he had a certain power level which he hasn't.
He's below YC1 for sure.

Even if you said is true ( which isn't)

You don't need even a decent reaction speed to become top tier.

Big Mom is a good example

 

[Monkey D Theories]

law made a whole ass sentence before hitting doffy who had his hands free and still couldn't defend himself.

this is just weird anime logic

characters can have whole ass conversations in a war zone that happen in a fraction of a second.

like that chapter in egghead where Bonney and everyone were falling and the pacifista were aimed at them

Kaido did worse to Luffy in act 1. Shanks was at least serious against Kid.

But Kaido outright gave Luffy dozens of free hits before taking him out, and even then didn’t even use his DF.
