Shanks being a pure SM is ur own speculation that logic won't work for me ...for me based on manga Shanks is abit below Mihawk but is stronger as a normal fighter (It is my opinion Iam not stating this as a fact)...Shanks being better in haki wouldn't make him stronger than Mihawk in this case since Mihawk is stated to be the strongest swordsman. So using WB as an example is irrelevant. Is that difficult to comprehend? Mihawk = WSS -> Zoro defeats him -> Zoro without a doubt strongest swordsman. Not the opposite.
I remember u saying that WB using sword is no dif from using his weapon means any tool is the hands of WB is nothing more than a weapon to aid him ...what makes u think that Shanks can't fight if I replace his Sword with something else..?
I knw that Zoro is going to surpass him & he is the WSS.....Also don't forgot that Luffy is going to Surpass Shanks ...he promised that to Shanks which means that Shanks should be stronger since he is the goal of Main character /Cap of the ship...
My poin is if we saw feats from both of them then u can compare them & conclude that Sanji is stronger/better ,same logic goes for WB & dark kingHuh? We saw no feats from Whitebeard until the war. I guess this means Rayleigh is the better haki user since we saw him fight an admiral according to your logic. Doesn't work like that
Ofcourse he can stomp Luffy ..Iam not saying that he can't ...he is serious about killing Luffy & it is not a plot shield Luffy barely managed to escape from Mihawk ..it would be a plot shield if Luffy fought him in a one on one battle for abit more & survive...Current Luffy can stomp his old self without putting any effort. Current Luffy would be stomped by Mihawk. Mihawk does not need to put in any effort in beating pre timeskip Luffy. That's the plot shield for you
