Never go full retard dude.
It's not shit talking when you think that Zoro will never be pirate king and you explain why. Your post is nonsense, you missed all the points. It's not at all about what Zoro contributed to Luffy, that is not very interesting. It's about what Zoro is capable of doing as a captain, and his mindset wouldn't get him far on the path to pirate king.
I have no clue what Sanji all of a sudden has to do with this. But I guess because I have a Sanji avatar you must think I'm a Zoro hater. I have to disappoint you there, I like Zoro very much. If Sanji's defining moment was to bake a cake for Big Mom that is pretty cool actually, since he is a chef first. He was able to whip up a copy of the wedding cake in a couple of hours without the proper preparation and while on the move, even beating Streussen's flavor and satisfying Big Mom. That is cementing his cooking abilities among the best in the world. His dream is not to be the strongest in something he wants to experience all kinds of food and preparations, make people happy with cooking, deal with his family and get home to his "real family" protect women and find all blue. He made progress towards all goals this arc, so not a bad year for Sanji.
When you say "And he was talking about if Luffy happened to die it would make sense that Zoro would continue in his place. Dressrosa EVERYONE saw Zoro's power and the alliance would still follow him in honor of Luffy and his dreams. " you hit the nail on the head they would be doing it for Luffy and not for Zoro, thank you for making the point for me. That is exactly what I was saying.
Now next time you reply try to think before you put your fingers on they keyboard.
