Yes so much shame in losing vs a Yonko and his whole crew solo
Where was this established? They clashed equally before he went on the voyage and got stronger. At the end of his voyage he was miles stronger and could tell if he was weaker than WB. He didn't think so. Try reading a bit
He was introduced as WSM, a title he earned in his prime. That doesn't mean he was still the same man. We know from the Ace novel that he was far from his prime. And no, titles are not word of God, they are in-verse perceptions. Besides WSC>WSM
Do you really lack such basic reading comprehension? Croc says he is weak. WB then agrees by saying he can't be strongest forever. He isn't disagreeing with Croc. He even says if he can just save Ace then it should enough because he is only a man and isn't some forever monster.
The translation says "None can doubt that in a one on one, Kaido will be the victor". The 'none' part means that is the predominant view among the people in the OP world. It isn't some baseless rumour.
Your attempt at downplay is incredibly soft
. Like I told you before, if you believe MF WB was the WSM then you are a retard.
