(Only their vampires and liches are strong, and that's it)) although the ghosts are not bad either) Archers die quickly, zombies are slow (Death with scythes are mediocre) useful when there are few of them) Use Death Grip to kill dragons) Dragons with their damage... what are skeletons, really?
Zombies are slow, yes. But zombies are like tanks. They are very durable and not bad in attack either. Even level 1 zombies pose a danger to many. It is very difficult to kill dragons in melee combat, even if there is only one dragon in the squad. And the attack of dragons is so strong that it's scary...
Ghosts are really cool guys, but they have low defense. So if the attack is successful, it becomes difficult for the ghosts.
In general, as I think, defense is the biggest drawback of necromancers. But in my opinion, it doesn't bother them too much...))
