What? You're not making any sense.
Oda tells us Mihawk is the WSS in name and reality. Now tell me Oda is wrong.

Also,
final villain can have a DF to be far stronger than Mihawk
For example:
Mihawk might beat Fujitora in a 1v1 swordsman combat with no DF extreme diff, that way Mihawk is still WSS.
but then if Fuji uses DF that has nothing to do with swordsmanship, he can low-mid diff Mihawk without you getting ass blasted by the title
