I agree with you on the Doflamingo part that he may choose to betray Kaido‚ but there are two things I am sure of...Kaido will destroy Akainu worse than the old sick Whitebeard who couldn't even Coo Squardi's attack...even if they lose the war‚ Kaido destroys Akainu one in one.
Does it matter if Kaido can beat Akainu in a 1v1 when there are 5 other Top Tiers (Aokiji, Kizaru, Garp, Sengoku and Mihawk) on the Marines' side?
Why would Akainu arbitrarily take on Kaido in a 1v1? Last I checked, Akainu would have no qualms about dog piling Kaido 6 to 1. Akainu does not care about arbitrary duels, he cares about putting criminals in body bags by any means necessary.
Second‚ Queen's Plaques...if he actually used them smartly‚ he can even put the admirals down with the plague‚ it is not like they are immune to it or that haki will protect them from it
Yeah but if we have One Piece characters actually using their brains then the Marines then have way more hax tricks up their collective sleeves.
If the Marines in general played smart then they could wipe out the majority of the Beast Pirates' forces by sinking their approaching ships. Anyone who cannot fly would be fucked.
Or how about putting Hancock against anybody who gets slightly aroused? One errant erection and BAM! Dead.
Or have Moria teleport behind any notable Beast Pirate that is engaged in combat and have him steal their shadow? In daylight, that results in disintegration. Imagine how big Dragon Kaido's shadow is? Moriah disconnects that from the back end and suddenly no more Kaido.
Doffy meanwhile can just flat out turn about 95+% of the Beast Pirates' own forces against them. Hell, considering he could stop Jozu dead in his tracks with contemptuous ease then anybody below Calamity is easy game.
Besides, are the logia Admirals not the absolute worst targets for Queen's poisons? Their bodies consist of a completely disposable element unless they are hit with Haki but good luck getting past their CoO and range. Even then, if the poison hits a limb then all of the logia Admirals would have no qualms about ripping off the affected body part and replacing it with an elemental prosthetic.
Meanwhile, the rest of the Beast Pirates are getting dog piled because Kaido brought with him only a fraction of the heat that Whitebeard brought to Marineford.
