The thing with Roger is though he’s not a swordsman in the same vein as Mihawk and Zoro, if that was the case it would have been made clear from day one.
With what we got, Roger wasn’t known for his swordsmanship he was known more as the guy who did the impossible by finding Raftel, matching someone like Prime Whitebeard in battle etc.
Swordsmanship is not something that comes up in the grand scheme of Roger’s character. One panel showing him displaying some swordsmanship isn’t going to suddenly change that fact.
Because of that, Zoro’s end goal simply has nothing to do with Roger because he’s not
swordsman first if you get what I mean. Guys like Mihawk, Vista, Zoro,Law, Fujitora etc are and have been specified as such. With Roger he’s not been potrayed that way, neither has he ever been labeled or specified as such as well.
also side note about the GOAT swordsman statement, according to
@Den_Den_Mushi , the raw text doesn’t say that. I would ask for a translation from Den on that matter though.
