I didn't know Crocodile will be proven a threat to Blackbeard.
I will say this, Hancock has the superior hax by far, but at some point, up the powerscale ladder, this hax becomes useless
It would work on a mindless crook like Teach sure, but this one move trick is not gonna have a say against a 'normal' top tier e.g. an Admiral or a Yonko, you won't see them drooling like Vasco Shot lol
Mihawk is a legit top tier, you can throw him against any character and he'll perform at his best every single time
So if you wanna say Hancock is pretty powerful and has the most dangerous ability in general then you may be right, but when you speak of top tiers then the bar is too high
Hancock is closer to Moria/ Jimbo than someone who gives EoS Zoro a high-ext diff, think of it this way
Hancock got hyped by both Sengoku and Aokiji. Doflamingo only got recognition from Aokiji lol.
Aokiji's hype was regarding her status as Kuja royalty, while he hyped Doffy as a more special case as a former CD, nth to do with strength
Sengoku was concerned about all Warlords in general, but yeah Hancock is powerful no denying that, but as I mentioned above it all boils down to characters being able to perform to the best of their abilities against any matchup
