Because honestly without all the crap bias. Zoro is not the mc and he can never beat Luffy’s opponents. Can you imagine Zoro beating Kaido now? No. Can you imagine Zoro beating BB or imu. No.
Luffy’s the only one who can finish the job and he was always stronger than his followers.
I can imagine Luffy beating Mihawk (Zoro’s endgoal) though no problem. Luffy will always be stronger combat wise.
Well lets go back to pre TS and I'll be serious and willing to change my mind if you would be open minded and not agenda filled.
Zoro would have wrecked Arlong or Kuro the only opponents Luffy defeated in fair fight
Luffy defeated Crocodile with heavy plot help and Enel are we really gonna talk about him?
Zoro vs Lucci I am not sure but I don't think Lucci can survive Ashura but when then Luffy barely defeated Lucci with Usopp plot armor.
Moria blew himself up
Can Zoro defeat Kaido right now? I don't think so but he can give Kaido a high diff fight since he mid diffed Kaidos first mate.
Now once he fully masters Enma he would have a chance.
But I don't even think Luffy can defeat Kaido yet.
Luffy being the MC is another reason why Zoro should be monster strong because only MC can have a subordinate as strong as Zoro.
If Zoro was an ordinary guy won't that make Luffy ordinary captain and not true MC?
is Luffy an ordinary captain?
