We can say we are close to the end but until we there for real it's not really the end game.. lt's putting time constraints when we actually
don't know..
You know Luffy is a special case, he's the main character who has to become a Haki Master and go through all the step for him to reach the top of the verse and beyond.. l'd argue Zoro and Sanji don't need to become Haki Masters, they need to find their Haki Niche.. Actually it's what Haki Swordsmanship is all about a specific Haki Niche..
Which Sanji will obviously be CoO related or CoC based CoO application.. Zoro will be CoA based CoC application which are the Black Blades.. And the more i've been talking about it the more apparent it's getting..
The thing with AdCoC is it is not a CoA based CoC application, it's a CoC based CoA application.. l hear you screaming and every Zoro fans - WHAT THE HELL lS THE DlFFERENCE! - .. Well that's where the Black Blades come in which are mostly going to be a CoA based CoC application and the best way i can picture it right now is CoC lnfusion or CoC Hardening on the Blade.. That's the Haki Path Divergence for Swordsmen aiming at the Pinnacle of Swordsmanship..
By the way you commenting helped me reach another level of understanding, thank you..
l hope everyone who reads this gets a nugget out of it..
Also in that same line of thought, Observation Killer would be a CoO based CoC application..
