Enma Zori's greatest power up in series took him from a weak YC3 level to mid YC1 level.
Luffy defeats Kaido Zori technically draws with King as they're both unconscious
Idk wtf your point is here
Enma is both nerf and a power up
On roof top he got AP boost but in return Enma sucked to much Haki.
So Zoro was YC1 in Dressrosa and YC1+ on roof top maybe due to Haki training
But then even Enma Haki boost that can permanently scarred Kaido, doing more damage to Kaido, much more than Luffy even with CoC Supreme King Kong Gun can do.
So then Zoro got one more power up and became a Yonko level character and stomped Kaidos right hand man.
Luffys offense is too weak bro
