Why is there abyssal lich the worst summoner in the game

Can the abyssal lich be changed. The lore says the well of souls is the source of all necromancy yet if you wanna go summoner it gets rid of your minions for temp buffs? Also can we get reduce reservation back over efficiency bc efficiency is way worse

It is insane that there arent more posts about this. Fighting a lord of necromancers to get his power, only for none of it to be related to necromancers or the abyss is just so tone deaf.
