Probably going to be a spicy take lol
Corpse shatter is just about the only case where using the tools we have actively works against you, and makes certain items undesirable. And for some reason a LOT of the items you’d otherwise want to use on a hork barb or their merc are undesirable
It really wouldn’t cheapen the game or be OP if you could run Death, Raven Frost, and Reapers on a hork barb same as with any other melee
