I might view you as a another Lanji stan sheep, but in this case, you are damn right. Credit where credit is due.
I find it funny how people complain about haki being 'too common' yet they forget that the devil fruits themselves were supposed to be so damn rare that most people would spend their entire lives without seeing one. And now there's several new devil fruit users introduced per arc. Oh the hypocrisy.
According to Wiki, there are 165 Canon Devil Fruit users introduced. How is in planet with probably billions of people, is it not rare? Alabasta itself had 10 million people in it. People Assumed CoC is rare without thinking much about real statements made around it.
One in a Million means it is not statistically impossible for Alabasta to have 10 CoC users in It.
Don Chinjao said there are countless souls on the sea ahead with Quality of King (Chapter 717).
Rayleigh said, "Most People who've made a name for themselves possess this power" (Chapter 597).
The above statements imply there are much fewer CoC users introduced than implied, not more.
