Be honest Zoro needing so much time for Lucci kinda change my view to his powerlevel.
It is not like Lucci is another Pica who stall and keep running away, he is a close combat fight like Zoro and he keep doing good job if even Zoro calls him tough.
Lucci is pretty close to Zoro powerlevel which I didn't really expected. Even if Zoro pulls out now everything, this fight was at least a high diff.
So where we place Lucci among the other Yonkou commanders? Do you see him stronger then King,Katakuri and Marco?
I think he is equal to them at this point, which make him at least a high high tier. Zoro is probably a inbetweener, above High High tiers(like King and Marco) but weaker then low top tiers(like Ben Beckman,Rayleigh).
Which that the gap between Zoro and Luffy seems large then I imagine at first.
The thing is, yes Luffy used G5, but he completely low diffed Lucci who couldn't even hit him for once and was a punching bag for G5. Luffy didn't even need adv CoC to beat the shit of Lucci. It clear to day and night if Luffy used adv CoC too, Lucci would end up like Boundman vs Kaido in Kuri, one shot.
Still Lucci is good strong and easily on par with other YC1 lvl characters.
Hope we get a full chapter with Lucci vs Zoro where both go all out.
Kizaru and Luffy are 2-3 leagues above Lucci.
