Agreed! As a suggestion I said in a thread "Spellcasting NPCs" that they should limit the ability to cast AOE spells to a certain group of NPCs like mages or witches and the like. And maybe limit the AOE area, decrease it a bit for certain spells. Like the Voidwoken, when they die they curse a lot of area with their blood, which can create a lot of chaotic nercofire around if there is a fire area present (which is always present cause they have a vulnerability to the fire).
