That wouldn't change much if Shanks only landed one hit on panel.
Plus, I hate the idea that Kid got one shot after everything he went through in Wano, it just reeks of Oda taking a fat dump on his own powerscaling. Like how are you going to hype up Kaido/BM for 100s of chapters for their strength, and then have Shanks demonstrate that he's far above them despite a lack of in-story strength hype compared to them, just to make him look cool? Zero integrity in that shit, would much prefer if Kid took a few attacks before falling to Kamusari.
