These resurrected corpses could only be salvaged for some top-quality materials or used as material for the Corpse Explosion Technique.
As for wanting to use the Necromancer's ultimate skill, "Rebirth," to resurrect the corpses again, that was out of the question.
The "Rebirth" skill required a wisp of residual soul and a relatively intact body, but these corpses, resurrected by some rule, lacked even a trace of a residual soul, having been completely expended.
Moreover, once these resurrected bodies were killed again, they would not drop anything. Their only value lay in the mutated shells of the Epic Bosses they had become.
Dragging them back for dissection and dismemberment could yield quite a bit of Epic-level material, which, for many life professionals, were undoubtedly first-rate materials.
