Moving the goal posts? This is what you said
Sure, I couldn't predict your though process to be unable to connect the dots, especially when you came up with random abilities which 1.) are already inferior than ACoC by default and 2.) doesn't make Zoro stronger whatsoever in comparison to his ACoC PU.
If ACoC was superior to black blades, Zoro would simply unlock ACoC at last because this would be - according to your assertion - the superior PU.
Yet Zoro unlocked ACoC first. Ironically, Zoro didn't even unlock ACoC for the sole purpose of becoming stronger, he unlocked it so that he can master Enma.
Zoro already unlocked ACoC but has yet to get future sight or peak CoA, so using your logic, unlocking ACoC is inferior a feat to both.
Except that is not my logic which you're using here.
