But we can actually say the same argument to Prime WB who was called "Strongest Man" Does that mean the title only relates to raw and brute strength?
Maybe other factors like "Speed, Haki, reflexes"...etc are all being ignored and thus the title isn't right.
But we all know that it's not true when it comes to WB title, as most guys if not all accept WB superiority over other combatant, specially if he was in his prime without sickness (excluding Pirate King naturally, the equal)
Point is, people only make those arguments regarding haki ONLY with WSS title cause god forbid if Shanks is weaker than someone, you know being weaker doesn't make you bad character. But some people, specially those two fanbases:
1- Shanks fans
2- Zoro fans
With all respect, but I feel that strength to them equates to "Good character".
While it's not, which is why for many of us, we accept what is given to us from Oda, and we only make arguement and question those titles IFFF Oda gave us reasons to question them like someone inside the story itself questioning the legitamacy of Mihawk title. But all the questioning is coming from fanbase who are desperate for Shanks glory
