Tf do you mean it's not? You used goofy vs lucci to downplay goofy.
Tell me why it's a low diff, are you the author? You're not even connected to oda so how the hell do you know the diff?
No I didn't. I used Nika vs Lucci to scale Lucci. Why the hell calling him YC1 would be downplaying?
I just explained why it would be low diff. Zoro is not even trying he is in base with 2 swords while Lucci is in his ultimate form. Zoro just called he will finish this now. Lucci didn't even hurt Zoro.
If you compare Zoro fighting YC1... After he unlocked CoC coating (chapter 1035) he low diffed King (I'm excluding the previous part from the analyze) because he didn't received one single hit from him. Maybe we could push to mid diff since he was trying so hard that he was getting tired so quickly to compesate the damage he didn't received from King in that chapter.
So it is similar scenario with Lucci instead Zoro is not trying so hard. I believe he will need to use at least one attack in Koh mode or Asura mode to wrap this up as he is claiming though what would configure into a low diff instead of no/negg diff.
