I honestly am surprised we get a "Luffy vs Kizaru" chapter before we get "Zoro vs Lucci" chapter.
Lucci said previously that as long as he and Kizaru are around, the SHs can't escape. This means one of them has to be taken down for the SHs to escape, and Lucci is far easier to beat than Kizaru is.
Also, I'm not trying to push an agenda here, but Zoro also won against Braham, Ryuma, Monet, Hawkins, Killer and Apoo without his bandana on. So, while I got your point, donning the bandana does not really equate with fighting his arc opponent. and, IIRC, during the battle royal with Ohm, he did not don the bandana until he was preparing his final attack, so maybe with Lucci it's the same with all these examples.
