A promise to a dead friend is still a promise. Her passing is the reason he has his most import sword wado to begin with
With zoro getting a power up + figuring out kings secret how long do you think the fight will last after that
We are just entering the Boundman vs Katakuri domain here. We still need to see:
- King being unmasked
- Zoro's training with Mihawk flashback
- King's lunarian flashback (which may double as Kaido flashback)
- King showing awakening and the extent of his hax
- The fight possibly spilling out to Wano/the capital
- Zoro vs King CoC clash
- Final phase of the fight
Basically, this fight won't end before 2022. Maybe even only several chapters prior to Luffy vs Kaido ending, especially since I think Luffy vs Kaido will be getting shown once Cook vs Queen and Raizo vs Fuku are done (hopefully before 2021 ends).
If we have the same list of top tiers then I don't see King ever beating any of them
Like I said, it can happen only if my guess about his hax is correct. Otherwise, no.
