Agreeing to disagree is absolutely fine with me.
This Zoro not going all out theory is interesting to me because we, as readers, do not know what Lucci and Zoro have been doing because it is all off-screened. Lucci is not some pushover, and Zoro, being as serious as is, would not waste time playing around. Plus, the wheezing, huffing, bruises, and dialogue suggest this fight has been more than casual.
