I don't agree with this made rule of yours.. What the difference between 2 AdCoC no touch clash and one AdCoC no touch attack?.. None.
The problem is that you are determined that Zoro does not have AdvCoC and anything goes to get it, whether it is using things that the manga never said or using colors in a black and white manga... Reason why practically you only think that, because you are forcing it.
No, first let's study Haki, stipulate the rules and then see which character has each thing. That is being impartial.
You're confusing CoA Barrier and CoA internal Destruction, both can not be used at the same time..
