late game ghouls will get stomped from AoE worst thing that can happen to necros is wisps but if they are down to sacrificing the heart of there econemy they already lost. plus ghouls dont have enough hp to tank late game sorrry but even a n00b elf with hunts and archers will rape you. just go fiends would be better with necros for a meat shield or in this case a bone shield teheheheh
