Dumbo
He wasnt dominating big he has his organs busted by law
On top of focusing on stiching them
Doffy was doing multi tasking
He was beyond nerfed
"He WaS nERfEd", are you fucking stupid "L"57? Then go and explain to me what difference would it make if Doflamingo was competely healthy except making him endure the attacks better? Does it increase his AP? His reflexes would be better, yes, but that's irrelevant when his only response was spamming threads worth of towns at him.
His other techniques, Flap Threads, were struggling to break base Luffy's hardening defence. Only his God Threads would legitimate puncture holes in Bound Man's techniques but that's a finisher - Katakuri didn't use Zangiri Mochi on Bound Man either.
I know he was nerfed you genius but guess what, I'm gonna stick by the facts. I could also go on and argue that Katakuri would just 100% dodge all Snake Man hits with no issues if he was healthy. So use arguments instead of relying on your fantasy.
