1.Im talking about facing other crews.....not just one guy. So if the strongest from Buggy's group is not stronger than the other crews Captain. They're going nowhere unless all the other matchups are blowouts which clearly wont be the case if they're facing Yonkou level crews.No it's not the same thing. At all. That analogy makes no sense.
Why does one person need to be Yonko level? I said it before, Buggy doesn't need any one person to be on the level of a Yonko. Anyone with enough charisma and influence can simply gather a large enough fleet and number of subordinates to match or succeed a Yonko's influence and strength through sheer strength of numbers.
That part about you're only as strong as your strongest crewmate? Two major flaws on that point.
1. Is that why the strongest member of the Strawhats couldn't beat a Pacifista on his own but the entire crew combining their power could?
2. When did I say Buggy was the strongest between him and his subordinates? He clearly is not, seeing as Buggy wasn't even worth the same level in the prison as they were, and Whitebeard himself dismissed Buggy but said the ones following him would be a pain in the ass to deal with.
2.Who said Buggy is the strongest from his group?
And no gathering a large fleet is not gonna defeat a Yonkou level crew. Not happening. Doesn't matter how many good fighters you have, you cant overcome great fighters with sheer numbers, not in this verse.
