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 
Rare UlyssesT L.
You can pry my proper ironsights from my cold dead hands. I will go further to say counterstrike 2 is cowardly pandering to esports purists. They should have gone the route of making a better R6 siege without the garbo ubisoft hud shit.
You can stand by that that all you like, but if you chant it the way
also chants "trigger discipline" and "magazine not clip" for tacticool approval points and Le 
Gold, I'd call that a rare Nakoichi L in return.
Also I appreciate trigger discipline discourse when it comes to little details like in the x files how Mulder has terrible trigger discipline belying his character as sort of a crank while Scully is the consummate professional with her firearm handling.
That's fine.
It's like those Burgerland Doctor Who fans that just word-drop "DALEKS LOL" and/or "SONIC SCREWDRIVER LOL" at the slightest opportunity.
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.
This. I'm ok with older games without ironsights, doesn't distract me, but a modern one? Just put that damn thing on your game fuck dammit.
It would be an utterly different game. It wouldn't be counter-strike at all.
