Why are dudes clowning on Zoro for Lucci blocking his attack? Yeah Lucci was in base, but Zoro is using only armament haki and two swords.
Lucci was able to clash with G5 Luffy using armament haki as well.
The reason Lucci got low diff'd was because of massive CQC gap between himself and Luffy, he was able to contest with Luffy in direct clashes.
