As much as I want to be happy for Kidd and Law in the latest chapter, from a writing perspective it's questionable how they came to defy their own rules of their df awakening. They have been saying for the third time this is the last attack, and not only that, they have been KO'd and attacked repeatedly even when KO'd until BM dropped the magic word "going to rooftop" and they suddenly are up and fighting her.
Same with Luffy, Ragnarok KO's him, a chapter later he's up and fighting with his CoC coating, later on even outright taking a Ragnarok that hits harder straight to the head.
People always say "willpower" but if that willpower logic somehow equates to haki, then equates beyond Luffy even to Law, Kidd, why not Kaido, or Big Mom then and have them push through overpowered attacks then, where's their willpower.
