You think Shanks and Mihawk are equal due to the fact they sparred ages ago at an even level. It's obvious Shanks has more to his fighting abilities other than using a sword his Haki is boss and I'm willing to bet far greater than Mihawks. The fact Mihawk himself Luffy's goal was harder than Zoro's should have been the moment people realized Luffy would always be a little stronger than Zoro.
Actually the way the author has designed this story is to show exactly what Mihawk stated becoming the Pirate King is a lot harder than becoming the WGS and in extension should give us a good idea where the character are and will be later in strength.
ok show me facts of shanks using other techniques.....and answer this rhetorical question...when akainu was stoped by shanks..why did he choose to stop him using a sword? and not hi s other "awesome techniques?"
don't get me wrong....shanks is preety powerful but most guys overate him just cause he is yonkou. you should remember that his crew plays a role in him being yonkou and being that they are few in number, it should attest to their strength. When he joined the MF war he didnt come with alliances like the WB pirates yet he stopped the war cause of his strength and that of his crew.
now remember mihawk rides solo.....nothing i have read shows otherwise unless he rides with a crew of monkeys.
nwy as i sed earlier, these are blanks left for readers to fill in to keep readers interested, otherwise the outcome of shanks v mihawk would have been stated just like they did in sabo v ace!
and as 4 the goals thing, being that Luffy's goal i think its been clearly explained.
as for the statistics used in OP, they are not black & white nor written in stone, because if we go on with that argument we will conclude that caribou is stronger than zoro and sanji just cause he has higher bounty.
