Before anyone gets pissed or anything, Zoro is my favourite character and that's never going to change (unless Gin shows up again) but I don't think giving him conqueror's haki is necessary, and personally I would prefer it if he didn't have it. Firstly, I think the reason why a lot of people like Zoro over Luffy or Sanji is due to him being slightly more relatable in the perspective that he's just a normal guy with a big dream and has achieved everything through hard work and determination with no help from a devil fruit or a raid suit (Ik Sanji only recently got it but still) and him getting CoC (since u can only be born w it) will kinda defeat the whole point of him being a "normal guy". Also, neither Mihawk nor Ryuma have been confirmed to be CoC users which means Zoro doesn't necessarily need it in order to become the greatest swordsman
