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 mean,
is how I feel when I see a sudden explosion of trigger discipline word drops in the internet wild, too.
Okay but consider it is, hands down and without exception, the most important safety practice when handling a firearm. It should be hammered in to the heads of every person who might encounter a gun.
I agree.
It's still annoying to me when it's barked out by a bunch of approval-seeking internet tacticools because a picture of a gun appeared on the screen.
