Please fire this guy. This article is nonsense. Statistically speaking we're immensely far away from the 1 in a million users of Conqueror's haki as far as characters introduced in the series. As far as we know the use of Haki as a whole, even devil fruits is still rare within the universe. The writer of the article doesn't seem to understand that because we're following the protagonist and are nearing the end we mostly only see the top echelon of warriors within the One Piece universe. There's no use in fighting fodder antagonists this deep in the New World. I don't even know how Oda could even fit it attractively in the narrative because the weak perish pretty fast in the New World.
