I don't think i understand what you're saying, can you clarify it a bit more?
Sorry if I made it confusing, english is not my first language. In short, I don't believe Future sight would make that much of a difference since when luffy had trained and had future sight, Kaido still was too fast.
Been rereading to find stuff but just to be clear, I believe that its completely clear that Kidd and Law downscale from Big Mom generaly and that in Wano the only one that could match their performance was Luffy, and maybe Yamato on his strongest form so I wont bring them up since they kinda exist in a vacuum for me. If you think that Wano Zoro has better scaling than theese 2 or that switch in Kidd/Law they would have better chances, Zoro would have a decent downscaling to Yonko tier better than WCI Luffy and Kat.
Also, even if base Luffy is not equal to his previous bound man self, there are other ways to put King and Queen that much stronger than Kat that kind of breaks WCI Kat scaling to higher tiers.
When they ever manage to fully react to a direct Thunder Bagua from Kaido in the Rooftop? As i remind you that his attack speed with Thunder Bagua does seen to be far greater than his regular combat speed.
Zoro, Luffy, Law, Kidd and Killer never tried to direct confronting either Yonko alone and only fight in group so that neither Big Mom or Kaido could trully focus on a single targer,
while also assisting to counter when it was not possible to dodge it in time, and even that in many cases
they did end up getting hits before they could react.
And for Big Mom using her in general its not the best scaling, considering that in Wano where plenty of people who despite not be on her level they somehow manage to dodge her (like Base Luffy back at Udon) or even hit her before he could react (Franky in his car)
The antifeats are strong with Big Mom, but I would take feats on Rooftop and in her fight with the Duo as valid.
I will also say that, at the start of rooftop, kaido states that now luffy can "put up a decent fight now" after his Thunder Bagua, I will simply say that, since Kaido has a habit of starting small and then working up until he peaks, and that Big Mom should be Comparable to Kaido with 1 homie (their stalemate at the start of Wano) and to Hybrid with 3 (roofpiece implies that and she has a combined attack with him so), Zoro cutting Heavenly Fuer before reaching Luffy; the 3 captains being stupid and showing comparable reactions to the ranged version of the previous attack; G4 Luffy getting Dragon Kaido by surprise after Kaifu; Zoro saving Luffy from 3 homies Big Mom (all of this are in the 1001 to 1009 chapters range, don't know how to show scans on mobile) are all valid feats that put them on a speed that should be grater than early wano G4. Also, most feats you posted are on
Considering that Luffy had to go under training to improve his Haki before he could unlock its advance applications we can likely assume that his Haki has improven in general, by an unknown degree but it still better, not only that but Emission itself further improve the user's defense than normally.
As when Luffy did unlock it,
we see him be able to survive a blow from an enraged Big Mom in Base, compare to the previous arc where a Boundman Luffy could only briefly manage to
briefly clash against Big Mom's Armament Haki before getting knocked to Base with little effort (which is still more than what Zoan Queen manage to do), which show to much Emission boost the user's defense.
There its a reason why Sentomaru claim himself to have the strongest defense in the world by mastering Emission, which we see that it allow him to block Kizaru's attack and even hurt him in an occassion, sure he lost the fight but because he could only compete with him by abusing his Emission as without him he was getting overpower quite quickly.
Not gonna disagree but, when he did that with emission, he put his hands up like the admirals on marineford and most if not all hits he took he did not do that and just took it. All emission feats that I remember are either offensive or hands up thingy, if you can show someone (better if its luffy) doing it not in either of those thing then thats that. (and doesnt that proves my point? If his emission made his haki so strong its kind of comparable to his boundman feat against BigMom? Pretty sure you can also chalk this up to being amnesiac BigMom but I don't remember if its her O'lin persona or not)
The hits Base Luffy took which didn't knocked down where non named attacks, clearly inferior to his Thunder Bangua, and the moment he did got a direct hit by an named attack (before he has the chance to guard on) he got knocked out, so no indication of Base Luffy had become more durable than his Boundman.
Luffy, in 1001 I believe, took a thunder bagua to the head and got up moments later and Kaido says "now you can put a proper fight" or something like that, and since the more the fight went the more Kaido got excited, the less "he held back"/"let out more power" and any feats are to be more impressive than what he did to him in EW(early wano) G4. We also have Zoro and Killer getting up after taking Big Mom lighting. Any attack that does not knock them down for good is a feat better than EWG4 and that scales to other characters (I can agree that Thunder Bagua is a good speed amp, but don't see it as a strong Ap amp, if it was his stalemate with LinLin would not be a stalemate if he has such a big amp in speed and power casually).
Again, even if its not base Luffy doing the cliff, Zoro and the rest of them still have a better general performance against the yonko than what EW boundman. Maybe not a blitz, but Zoro would scale in such a gap in strengh and durability that, when King rocked his shit, shifts the weight in the Lunarian's favor.
I agree that i might have overblown some stuff due to misremembering some stuff, only reread the roofpiece up to luffy using acoc, but after that is Zoro is down and luffy actually got a power boost that is on par to his G4 in base, so most of the avenues on backscaling are gone. I also see that the powercreep isn't as big as its made to be, but I still se it there, not Base luffy being G4 level but trough the others performance (mostly Zoro) being far better than EWG4 and other characters scaling to him.
Again, I would not have a problem if the wiki made it not like that and took your pov since I see as mostly valid and is in line with the "narrative" .
Like as I said, I too a controversial view that Big Mom deserves more and has shown more than what we give her here and should be closer drunk/buff Hybrid with her amps.
All in all, the "powercliff" should be discussed more
(Or maybe not since everyone upscaling From 6B, kat might actually be 1/4 the ap value from base Big Mom or something). Thanks for the patience and sorry if i made no sense or sounded rude. I'm still traing my english writing
