So when Oda first explained haki, you had 3 distinctive and unique colors. Armament, an invisible aura that can be used for offense and defense; observation, which gives the user supernatural perception; and conquerors, which allows the user to dominate others with their will. 3 distinctive powers, 3 distinctive abilities.
Yet all of a sudden, it seems as if conquerors has become armament 2.0. You can now coat your attacks with CoC. What does that do? Fuck should I know. Not only Luffy, but now zoro can use this power as well and yet Oda hasn't bothered to explain what CoC coating actually does. CoA coating makes your body/weapon stronger, but how can CoC coating do that when CoC doesn't work the same?
Perhaps CoC coating makes your opponent weaker instead of making you stronger? Sure would be nice if Oda explained this ability before giving it to both of the MCs.
But even beyond this, I still can't help but feel like the very concept of CoC coating is fundamentally a betrayal of what CoC was portrayed as and what it should have been. CoC never needed to be CoA 2.0 that can just be slapped on to any punch or slash to enhance its strength. CoC was fundamentally the power of controlling others. The fodder control aspects of CoC are absolutely broken in a war scenario and if Oda cared about such things, it would have been really cool to see CoC actually play some role in the strategy of the onigashima raid. Wouldn't a major objective in war be for CoC users to KO as many people as possible with their abilities?
ACoC could have taken this power to the next level. You could be able to force people to do your bidding, exert control over yourself to surpass your limits. possibly even exert control over your environment to manipulate it.
I feel like overall, CoC was a unique and interesting ability that should have had a major impact on the way wars are fought in OP, but was instead dumbed down to "CoA but stronger", for no reason.
