Then we'll hear "despite Shanks's godly CoC and Rogers's Haki stored in the blade Mihawk's blade/Haki is superior to Shanks/Roger and that Rogers's haki is carrying Shanks etc etc"
If it turns out that way those are definitely going to be thrown around.
I don't care who said that about Zoro or who will say it about Shanks :)
Shanks using the blade of Roger AFTER he became a Yonko can have a massive plot behind it ...
that plot interest me FAR MORE than any new power level bullshit people gonna use
Shanks is using 1 of 12 swords
Shanks is heir of Roger HAT
he don't need this sword to prove anything
power or
personality wise , but
plot wise? yup
