I don't see how Shark would be worse? Are you thinking chainline issues will
increase wear?
I definitely noticed I wear out cassettes faster with a 1x system (any 1x
system). It makes sense as the loaded pedalling (grinding uphill) is
concentrated on fewer cogs than with a 2x system where in the granny a wider
range of the cassette is usable climbing.
I know two riders well who have gone back to 2x (one with a FD and one
manually shifting between a NW 36t and NW 26t because he likes chain retention
and lack of front shifter) for specifically the wear issue you note.
It can be a total PIA. But in the shop I had good results just replacing the
upper cluster on Shimano XT and XTR cassettes for riders who wore out those
cogs but otherwise had pristine cassettes.
