Mihawk's entire portrayal is leeching off everything Shanks does.
I think that's a bummer, since's he's a cool character, but it is what it is.
Marineford didn't do him any favors. And Cross Guild is just Oda's roundabout way ot shoehorning him into the story so his fight against Zoro isn't some lame sidequest and can actually be part of the narrative.
Mihawkbros should unironically wank Shanks harder than Shanks fans since they depend on him to get indirect portrayal.
