They serve a couple of purposes:
1) When you get a bunch of them, their mass ranged attack does reasonable damage, without the time it takes for Horrors to stumble over and start swinging meaty paws. Add Favorable Winds and/or Winnowing to boost their attack damage. Three or so? Try sixteen for real fun.
2) They're not as effective as Horrors at tanking, but they _are_ meat shields nonetheless, and return energy to primary Necros via Reaping when killed, so in a way you _want_ some of them to die now and then to refuel your energy.
3) The Fiends you raise are corpses that enemy Necros can't exploit against you.
