If Luffys progression was decent
We wouldnt be complaining as much as we are doing now
Confused though, what is wrong with his progression? We see him lose to Kaido in the beginning of the arc. We see him train for 2 weeks regarding advanced CoA. We see him finally hurt Kaido in chapter 1000 with this application. We see him nearly STILL get 1 shot several times (to which he technically gets knocked unconscious in 2 cases), consistent with Kaido's strength.
Are people upset about AdCoC? Yes, it is something Luffy learned mid fight, but its a complete callback to Rayleigh's conversation with Luffy and how haki blooms in battle, along with the fact that:
- Luffy is a master at learning new tricks mid fight by observation (see how he explains how G2 was made up or how he got around Enel's mantra).
- AdCoC is just a larger overall application of AdCoA. It's another level. He simply applied that level to something he's already had.
