Who else has enma? its not his acoa doing that; its literally enma itself. But acoc having on their weapons is a general thing happening to all characters, including Kaido, Yamato, and Luffy, all had it.
You compare zoro using acoc to everyone else because there is nothing that makes zoros acoc special. it's the same with everyone.
Zoro unlocked it and had trail in attacks before this one.
Luffy used it to trail some attacks, but it didn't have the same thing with Kaido.
Get your head off your agenda.
