And Kuzan showed us that an ice punch + armament can match a CoC punch from Old Garp
A young Garp, with skysplitting CoC, is on a different level.
Again, ACOC isn't something special hax or narrative speciality indicator like Gojo's limitless lol
When Luffy showed CoC in Marineford, Oda showed every Admiral, Garp, Sengoku, Mihawk and Whitebeard react to it. Marines said that he will become a powerful enemy of the Marines right after that.
What did Doflamingo say when he compared Luffy & Law? "Luffy is a CoC user, his potential power is even greater than Law"
It's really simple. At the highest level, CoC users stand above the rest.
