That’s to show that having a black blade doesn’t make you weaker than guys with it
And my other point was : Roger and Shanks indeed only used swords, are swordsmen but there are not in the WSS race and not part of Zoro dream
there are 3 possibilities
but i'd preface it by saying the Marines are talking about clashes that Shanks had wth Mihawk a decade ago since there are no recent or novel accounts of their altercations .. so based on that they either think that
1) Mihawk had superior skill to their knowledge and assessment of their duels a decade ago,
2) they think that shanks loosing an arm made a difference enough for them to conclude what the spoilers illustrate.
is it a safe to say that Mihawk is superior in swordman ship than Shanks? ... i think its a safe bet given it had more weight and still maintains it, but its not realistic per say given their accounts are a decade old
there is a chasm between 1.04 billion Shanks -and 4 Billion Shanks that pulls up on Yonko's and Admirals and makes them tactically retreat.
if current Shanks is a able to do such then who's to say the out come in a 1v1 is surely in Mihawk's favor not knowing how skilled Shanks is with his one arm.. who could've ended Kizaru just THAT CASUALLY
to me its still an extreme diff either way.. i can't jump on details based on outdated duels and assumptions..
These are the same Marines that made Buggy a Yonko based in a advert poster
the baseline in there is no way to know how skilled Shanks is now or what style he has developed really.
