I'd honestly wait to see Luffy performing Katakuri feats before saying he's the same level as him. We've only seen him consistently reacting to events happening in the very next moment. He can see the future perpetually, just not several seconds. Even with Kaido's Thunder Bagua, he barely had time to react despite supposedly "having Katakuri tier FS".
Even in Udon, he was calling out attacks just a moment before they came. Katakuri's initial display for FS was him calling out a couple sentences, and witnessing 2 deaths moments after.
Doflamingo only got blitzed once by G4 Luffy. He blocked the Kong Gun, he still blocked Rhino Schneider with Haki despite losing sight of Luffy, he straight up dodged and counter-attacked when Culverin came, but he still got hit since Python is a homing attack. He then proceeded to fight Luffy for 20+ minutes after this, so I am totally against saying Luffy was blitzing. Doflamingo wasn't equal to Gear 4th in speed, but he was able to keep up for most instances.
- I agree for Kenbun Haki, but do keep in mind Doflamingo isn't exactly trash with the ability. He was still able to see everything going on out-side of his vision, and blocked all of Law's ambushes (minus Gamma Knife, go figure), and could block against Gear 4th Luffy who was in his blind-spot. He's at least got good sensory powers.
- Doflamingo's Buso should not be underestimated. It is potent enough to ward off Law's ROOM attacks, which only the Yonko so far have better feats against via passive Haki alone. Base Luffy's Haki at the time was no match for Doflamingo's (ignoring Flap-thread, as it's quite unfair for both--but Doffy still won that case) and he was overpowered almost every single time he tried to block Doffy's Haki attacks.
- He matched Doflamingo who just got organs bombed 5 seconds prior. Even if it's 2 keys later, it's not entirely confirmed that his Haoshoku got "more potent", just that he finally learned how to use it properly--and in a way we never see Doflamingo use it, so he'd wreck whether his Haki is weaker, equal, or superior.
Doflamingo was flying in chapter 783 despite Luffy being restricted to the ground. But I'd also like to point out that Doflamingo never flew in Marineford (he was for a moment during the Shichibukai double-spread), and I think this was because he wanted to keep his ability as mysterious as possible. It is in-character for him to use flight.
- Edit: Also, he used it against Law towards the end of their final fight. He was disadvantaged since he received a blow and was also surrounded by debris that Law could use TK on, so he took to the skies to avoid being disadvantaged further.
Luffy can't dodge with ease if he's inferior in speed, especially if Everwhite comes into play, making the entire ground dangerous.
You bring up a weakened Luffy, but do keep in mind this was the case for Doflamingo as well. They both commented how the other was barely able to stand. Their Haki and power behind their attacks were definitely limited. Saying Luffy is ~ but slightly < Doffy's Haki based on that one instance is unfair when Doflamingo was clapping Luffy pre and post-gamma knife in the Haki department.
Luffy's Haki DOES take him a long way, but I'd like to say he doesn't have anything outside of Durability that can match Doflamingo outside of having blatantly superior Observation and Haoshoku.
- Also, Doflamingo can still hurt Luffy since the latter isn't using his Gear 4th Haki + Rubber melding, so Doflamingo's blunt attacks wont just bounce off. It's just ~/>3.98GT vs >4.3GT. Not big of a gap by any means.
Edit: I would genuinely like to know what Luffy would do against Awakening without any of his gears. He can dodge, but once the ENTIRE ARENA is turned into string, it's going to be a repeat of chapter 790, only this time he wont have G4 (or any of the others) to break free from Doflamingo's threads.
- Yes, I know Luffy's got higher Dura than Doffy's AP, but the gap is quite small. Doffy is >3.98gt with Awakening, but that doesn't account for Haki + Awakening which he didn't (on-panel) until after Leo Bazooka. Even if he didn't have that amp, he's still strong enough to dish out damage to someone with >4.3gt durability.
