No lmao, luffy is the one who pushes the story, thats why the story follows him when they are separated, i guess this is the first story u ever read so u cant understand that, robin is the 2nd most important and she can reveal the place of laugh tale not nami, and shes not a main character, and if zoro moves the story with fighting how he is not fighting the major guys ? This is some serious cope dude.
Clearly we are not reading the same story then. It is true that Zoro is not relevant which is why i said "for some reason" but there is some importance to him to the story. This is not the 1st story i have read sorry to disappoint you there but. Allow me correct you here.
Luffy is the MC no Luffy no Story. Fighting in One Piece for Luffy has always been a fight with ideals not overcoming obstacles such as breaking steels destroying walls mountains. It was never the focus for his fights only ideals.
Zoro is the one in the story who struggles with said obstacles i mentioned above and all his progress on the story including Asura was testament against the Two Yonkos this arc. He Endures for Luffy's Sake "Hakai and conscious Zoro" "Rangarok and sleeping Luffy". While Luffy leads his way. Wano has become a wake up call for Zoro and it was his 1st Arc he fights the Major guy i wonder why.
Nami is the one that explains the journey and is the one to always give details of how the Seas works and she was the focus of getting to Major Locations in the story and the one to make it happen that Luffy reaches his Laugh Tale.
Now Robin and all the rests of the SH are important and KEY to Luffy's success to achieve his GOAL. Even Sanji is important but sadly you might disagree. Read the story again you might get a hint on why Luffy "can't become King of the Pirates without Sanji".
Now here is the correction for you to understand that without his CREW Luffy cannot Push the story:-
Ever since Kuma separated them. Luffy has been pushed around going with the flow but keeps falling short again and again and again. He couldn't fight to save he couldn't move around without stumbling on his head. No plans no support. But ONLY one thing that kept him going and that my friend is his quality of charisma and his will to challenge the IDEALS infront of him that kept making people help him but he still fell short in the end. Oda made sure to TELL you that when JIMBE a future CREW member woke Luffy UP to realize that he has friend that can support him. The whole flashback thing with Jimbe and Ace was ace telling him that Luffy has friends who can support him and he no longer needs to worry about Luffy because of them.
Now go back to Arlong Park which was in the Prologue of the Story where Luffy outrights tells you he can't.
Use Swords - Navigate - Cook - Or lie. BUT he can beat Arlong and his fight with him was an idea vs idea.
There.
