I had no qualms with Lucci, but Gear 5 Luffy low diffed him and without Haoshoku coating.
That caps Lucci very hard.
Like Lucci is automatically not on the level of people like Yamato (went toe to toe with a serious Hybrid Kaido using Haoshoku coating for much longer).
Man I've argued this 100 times already. Luffy literally treated Kaidou, fucking
Kaidou worse than Lucci in his initial G5 chapter. Do you know how ridiculous G5 is? Screw CoC Coating, that's for AP purposes, that doesn't magically make G5's ridiculousness any easier to deal with. Lucci was never kept down anyway so that's completely ok. If he actually got knocked out for good without CoC coating you would have a better point.
One more thing, Lucci was more focused on Sentomaru than Luffy. All things considered, way overblown. You essentially want a Kaidou + level performance from Lucci right away, which are ridiculous expectations.
