With a next update, They should really buff the Necromancer and turn it what its supposed to be, a pet class. As we all know, a necromancer is a summoner of skeletons & we currently don't have that. The class either needs a combat period pet or better yet pets and not some one hit or timed summons but rather auto summons pets while the sigal is active or they could do a perma pet/skeleton that adds a magical disguise in cities to not get guards's attention.
Or better yet, if they want to do the Necromancer a proper justice than the *** show we have, is turn it similar to Elden Ring's Marineers with the constant summon of skeletons during the battle.

They can either have two types of pets, timed summons that hits like a truck or have a permanent summon that auto revives itself once defeated like Elden Ring's Skeletal Militiaman Ashes that auto revives unless its defeated properly. In terms of ESO, they can auto revive unless the Necromancer is killed.

They could maybe pull a ultimate ability similar to Skyrim where it summons a temporary Necromantic Dragon, the same one from Labyrinthian, can't fly but can do quite a bit of damage in a short period, providing it to be a target, do aoe and single target damage but doesn't last long.
