1. They actually don't, especially Zoro he used a pretimeskip technique that has very weak raw power compared to Ifrit Jambe and Gear 3..
2. Sanji doesn't need CoA to use Ifrit Jambe.. And i'm not talking about base CoA on body part, Sanji can shape the form of his flames in sparks by infusing CoA in them.. If you don't consider AdCoA, that's fine..
3. No he doesn't..
- Zoro didn't do '' no touch '' AdCoC..
- Black Green, Black Red, Black anything lightning is CoA, not AdCoC
- Zoro's lightning trails when doing Dragon Damnation were backward when they should have been forward while charging like Kaido and Whitebeard..
- AdCoC attacks are close range and not flying attacks..
4. As i said in point 1, Zoro's attack was considerably less powerful than Sanji and Luffy.. So nothing can be inferred from this chapter..
