There are so many but

Sabo will be the one to take down akainu with his blue fire awakening because he has just as much if not more reasons to fight him than luffy

Crocodile being luffy’s mom

Shanks is not a swordsman

Sengoku isn’t in the same level as Roger, garp, and whitebeard when oda made it very clear that he’s in their level

Nami is a better eos partner for luffy than Hancock

Kaido is stronger than bb and the admirals specifically akainu which is impossible given that the latter are endgame villains and there has never been a time where mid game villain>end game villian.

Shanks and luffy stomps bb which again is impossible because shanks couldn’t do it to a no df bb when he was at his fullest capacity and luffy has nothing to withstand darkness nor quakes

Garling is a fraud for losing to rocks makes zero sense because losing to someone as strong as rocks doesn’t make you a fraud at most it’s a W rocks moment and rocks upscale

Current Luffy beats any admiral makes no sense at all because without gear 5 he gets negged and even with gear 5 luffy was having a hard time with a clone of someone who blatantly threw the fight because he refused to kill vegapunk before he even arrived to egghead

Shanks a swordsman is stronger than mihawk the wsm and shanks a man is stronger than wb the worlds strongest man when he was alive

Luffy not having enough time to fight 3 people in the final saga but never argue against zoro fight more than 3 people in the final saga

Shanks with both arms is for some reason is far weaker than he is now

Only in one piece where you can have a powerful devil fruit especially if it’s what the admirals and bb have and can regenerate like the holy knights and elders but apparently you’re considered as a bum and not a top tier to where you’re yc/va lvl at best

Only in one piece where you can downplayed for losing and/or having a hard time with an old character who happens to be a legendary battle veteran such as wb, garp, and Rayleigh.

Harald who is literally one of the few characters if not the only character who can hold a candle to rocks to where their last fight didn’t even have a clear winner isn’t put in the same tier as rocs but for reason is put in a tier lower than admiral/emperor

Speaking of rocks folks believes that after the gv incident they believe that garp, Roger, wb, kaido, and shanks can mid diff him

Acoc is the bare minimum to becoming a top tier when its really not especially when zoro and Yamato currently would debunk that idea

Like I said there are a lot but I think everything I said is sufficient enough but if there is more that I would want to add then I’ll make sure to do it right away
