@Voodzik:
Alright, then how about just to more fights? Remember, THREE ships went to the front to take down FF and Galle La and the Giants. That means there might only be two VA's here to fight, meaning just enough for Robin and Usopp, the only fight-less strawhats here, to each take one.
It'd make no sense. Once Enies Lobby is rased, the Buster Call task force will try to get Robin back. It means they'll focus all their strenght on the bridge of hesitation: they'll call back the three ships from the main gate, and the 5 Vice-Admirals will be available to fight.
And even if only two VAs showed up on the Bridge of Hesitation, there's at least 6 Strawhat who could still fight: Nami, Robin, Usopp, Franky, Sanji and Zoro. They want to get out of here quickly, so they wouldn't engage in one on one fights, they'll likely attack a Vice-Amiral at 3 against one to get rid of them fast.
I don't understand why VA's have such a reputation about them to be honest
We've yet to see a high ranked officer from the Marine HQ who wasn't ridiculously powerful, Tsuru excepted, but it's implied as soon as she's introduced that she's a tactician and that it's probably the reason why she's so highly ranked.
Those VAs look like fighters, they're the second highest ranked fighters of the Marine elite, doesn't take much to understand they're probably some of the most powerful characters in the One Piece world.
