I mean there was a marksman rifle in MW2 that I used religiously, you basically quick scope with it and it's a OHK.MW2 2009 was the worst I think. Fast ADS on sleight of hand pro that worked on snipers.
Quickscoping is annoying but it's always going to be in CoD. It's in every shooter to be fair. Best they can do is increase flinch to counter to it 😂
But you miss? You're done and you're getting killed. High risk high reward.
