In terms of gameplay mechanics, old school zoom aiming achieves the same thing as ADS. Is getting to press your nose against virtual firearms really that important in a game about shooting werevolves and vampires?
I blame this on the proliferation of Call of Duty over traditional scifi and fantasy shooter franchises. You can fucking ADS on an assault rifle in Halo now 
i will admit my shame: I am playing COD again because i get it without paying full price (game pass) and it scratches my current need for an ADHD hamster wheel
however, i am deliberately trying to unlock attachments so i can make the weapon builds from that one tiktok guy who exclusively plays with cursed guns that graphically break the game
