Not to be rude, but I think the problem people might have with "real Zoro fans" is exactly this. Mihawk implies that they haven't fought in ten years, when Shanks freaking came up. Shanks arrives at the war and Blackbeard with his fresh outta jail crew doesn't want smoke. The man has a 4 billion bounty. He's not gonna get beaten by freaking Mihawk just because Zoro is a cool character.
