An elite ability Kaido mocked Luffy for having?
When did that happen?
No it's just showing Kaido is not a reliable source as he can't even reach the full potential of his abilities
It does not matter because he is far more credible than the hopes & wishes of fans, being a Yonko, a pirate at the top of the food chain & among the 4 closest to the One Piece for decades.
And it's not like he doesn't know about DF Awakenings either, in fact he's the most knowledgeable one regarding it.
Kaido's argument only falls apart when you bring up an example of how a non-CoC user with DF Awakening ended up surpassing the Yonko & Admirals to rule the seas. There are zero characters like that.
The cope that there is no difference between a CoC user & a non-CoC user ended long ago in Wano when CoC started being weaponized.
It definitely matters, ESPECIALLY at the top tier level where the CoC users can weaponize it.
