Like listen, people can call me crazy or whatever but from what we’ve seen, yes Luffy has improved. But 6 days of practice with advanced armament and being able to see the future still don’t allow him to go toe to toe with a Yonko and win 1v1. Like people are taking the 5th Yonko thing to literally, it’s not like Luffy is at that level and even the 4 current Yonko know that too. Luffy struggled with Doffy, Kata, and Cracker, this can’t be argued. Luffy needed external help in all these encounters, this was evidently shown and at times even repeatedly mentions (e.g. Doffy vs Luffy). I’m not downplaying Luffy in anyway, his progression speed as we know is incredible and his talent too, but franky he won by the skin of his teeth in his last 3 main fights and even he knows and mentions that he’s in Yonko territory now and has to take things seriously, hence why we’re seeing repeated uses and quick bursts of G4, yes it’s strong yes it’s fast but it doesn’t last and we know this. Luffy doesn’t have enough time to take down a top tier just like that and still has to evade the enemy whilst his haki recovers. People forget that the Cracker fight lasted hours and G4 doesn’t even last that long even now and still has the same drawbacks.
Even with FS and AA, Luffy still barely dodged the attack that one shot him. If Luffy were fighting Kaido 1v1 he’d be dead. I can’t even comfortably say Luffy beats King and Queen in a fair 1v1 going off his last few fights. Sorry to say but that’s just how it seems and just how I’m seeing it lol
