math isn't your strong suit huh?
Top Tier:
Luffy -> his 4 commanders
Dragon -> his 4 commanders
Shanks -> his 4 commanders
Law
Kid -> Killer
Yamato -> 7 Scabbards
Marco
Cross Guild
Hancock
Rayliegh
Mid Tier:
Entire Fleet who will stomp any Vice Admiral or CP0
X-Drake
Koby
Giants
A bunch fuck of other characters
Low tier:
They are completely irrelevant to the discussion.
WG/Navy Top Tier:
3 Admirals
Akainu
5 Gorosei
Imu
Mid Tier:
Vice admirals
CP0
Low tier:
They are completely irrelevant to the discussion.
Top tier outnumber by at least 2:1 favoring the alliance.
In regards to Seraphim, they are controlled by Vegapunk so they are irrelevant. Idc if the hierarchy to control Serpahim prioritizes Gorosei over Vegapunk, that is just a red herring. If it isn't, then that is terrible writing because it makes Vegapunk character look stupid, knowingly creating technology that it is going to be used against him without any counter measures.
In regards to World Government having an ancient weapon, so does Luffy. He actually has two! So again the alliance outnumber 2:1.
I opened my post with "The WG consists of over
170 ALLIED COUNTRIES" Big brain IQ over here replies with" math isn't your strong suit. "
Do you know what a Country is? That's not a person. Those are Nations, each occupying thier own bodies of land, consisting of hundreds of thousands if not millions of people, and thier own militaries. In the real World they have their own individual governments, but in the One Piece World, those 170+ are all controlled by the World Government.
Doesn't matter how many names you want to rattle off, when the potential of the WG's forces are infinitely greater. Call me crazy, but I'm sure Oda can squeeze in one or two semi decent fighters out of the hundreds of millions, if not billions of people in those 170 countries.
I like how you undersell the Vice Admirals, when we know for a fact two of them are so strong, they were considered for the role of Admirals during the time skip. So that's two more top Tiers right there. And I guarantee you at least half of the known ones, are at least in the High tier range, and again, that's just the ones we know about.
The Seraphims will be apart of the WG forces. Don't know what kind of failsafe you are expecting. They are clones, not robots. They can not be reprogrammed. Vegapunk was a WG ally at the time he created the Seraphims. He had no reason to not program them to the WG's specifications of the Gorosei having total authority over them. Hindsight is a bitch, but what's done is done.
Luffy has one Ancient Weapon. Plutons fate is up in the air. The one the World Government has, has the ability to wipe a Country off the face of the Earth from thousands of miles away. Can the Sea Kings do that?
Yonko Commanders aren't Top Tiers, and Shanks EoS fate is debatable, as is all the other people outside the Grand Fleet that you mentioned.
And no matter what, there is strength in numbers. Hundreds, if not thousands of Pacifistas is a game changer. You had Whitebeard ally Pirates teaming up just to take down one, and those were the imperfect versions. Not even the Return to Sabaody Pacifistas were the perfect versions. We haven't seen them yet, but they are much stronger than the ones we have seen.
So I honestly don't know how you think the allies hold some kind of massive advantage. Even if you disregard everything I said, which you probably will, the good guys will always be the underdogs. There is so much potential on the WGs side, it's not even funny.
