@SuperJew:
Strongly disagree.
We just saw The Strongest Man in The World, his loaded pirate crew, and 43 pirate crews from the New World get curbstomped by the WG. And that's with minimal contribution from Garp, Sengoku, and two of the three Admirals.
If Luffy is going to beat the WG, he's going to need to call in all favors from the people who like him. The Revolutionary Army won't be enough, not by a long shot.
not saying we won't need help but lets pretend it was the FUTURE strawhats, the PIRATE KING LEVEL strawhats arriving at marineford to save Ace instead of Whitebeard.
i see storm clouds racing in and like hurrican or typhoon, and lighting going crazy all courtesy of Nami.
Usopp from miles away before we are even in sight shooting down people left and right with huge ass fire and lightning birds or whatever legendary pokemon he whips out by then, still missing articuno.
Then the thousand sunny flying through the air and landing past their initial defense and screwing everything up, followed by a gaon cannon blast.
And we have Robin with her thousands of arms to do random chaos around from flipping cannons in opposite direction to disarming people, to tripping to clutching, to who knows what else, her fruit is insane. Oh and not to mention if she had key she could sneakily with her hands unlock Ace's cuffs possibly wihtout them noticing.
And i'm not even bringing up the main fighter between new CYBORG Franky, MONSTER AWAKENED whatever Chopper, and Luffy, Zoro and Sanji.
Hell our crew alone seems way more intimidating and efficient than Whitbeard and his 14 commanders.
