Hard to call Luffy the mvp here, protecting Vegapunk was by his own admission his mission and he failed multiple times.
Not to mention the embarassing display of stamina, laid out in the middle of the battlefield after a brief exchange against Kizaru. Then there's how useless G4 looked. How useless he looked against the Seraphims too.
Strawhats in general have looked pretty bad so far in this arc. Luffy hasn't been much better, his single saving grace has been WSG.
Almost seems like we went back a step after Wano
so far. I think we might be getting to the serious stuff now though but it's extra pathetic knowing Luffy has been abusing his awakening the entire time and he's barely got anything to show for it, this is unusual even for Luffy's early arc jobbing standards.
