Serious.
Sanji doesn't have strength dream, so he can get stronger by gathering 7 dragonballs, wishing to be stronger and it still wouldn't ruin his character. Yet Oda writes him as this character who doesn't want a shortcuts to strength
Which is a total contrast compared to Zoro, who seeks out every possible shortcut to getting stronger, like magic swords. Which is jarring because his character is purely just about fighting and getting stronger, yet he has no self respect to get stronger with just normal swords
Zoro gets an unfair advantage to his road to WSS compared to his other rivals (whoever they are). There are
very finite number of graded swords and only lucky people can get their hands on them and gain their powers. Not to mention Zoro gets 3 of them.
So if Zoro's other rivals weren't lucky enough to get a good graded sword, they are automatically at the massive disadvantage.
What if a future challenger that challenges Zoro for his WSS title and only loses by a hair because he had a normal sword, while Zoro had 3 legendary swords? Wouldn't that show how much better swordsman who didn't use magic swords is?
And no, the "Zoro needs to train with them" excuse doesn't work because the "training" is done offscreen, showing how little it takes and in return you gain so much more power than you could ever get with training with a normal sword.
Kozaburo calls normal swords "crap"
If Zoro actually followed his character, he should throw his magic swords away and use "crap" swords to be beat Mihawk and prove that he is WSS without needing magic swords and can do it using any swords.
I have no idea how you can be a fan of Zoro and like him using magic swords. Right now, the road to WSS title is just about who gets stronger swords
