Agreed.
Also Duriel had cold attacks and auras in D2. Andariel was poison. It feels like they didn’t even play D2 to get inspiration for the source material.
Also, Andariel was scary in D2. ‘Die Maggot’. Now it sounds like she eats too much cheese. She could supplement with psyllium husk with a good amount fluids to alleviate some of the digestive pains she is currently going through.
