Actually if you push the thought further it's bad for Zoro.. Y'all are saying Oden was an AdCoC user and he was in his prime, so he would of been a master at AdCoC, and he should have used full Red CoC coating Lightning instead of Black Red Lightning if he had AdCoC.. This sort of prove that Enma and KoH are not AdCoC but CoA all along..
Now relax with the Oden does not have it and Roger using Divine Departure isn't AdvCoC. Even if you say he was talking about Roger not Oden then check mate buddy Divine Departure is AdvCoC.
Colors means nothing. You either have it or not. Now that Oda have confirmed your FEAR about Oden and Roger's Divine Departure being a AdvCoC attacks.
Go with the flow follow Zoro's panels one by one.
Zoro : use all haki = fodders knocked out = CoC confirmed - Blades covered in lightning like Luffy/Kaido/Roger/Oden/WB.
Now the above line is in bold font is a fact from the manga and that happened you can't say its wrong.
Now go sleep
Are you going to Deny Oda's own words now?
