I never really got into any of the other CoD MP games so I'm not sure if it was always the same. But seriously a OHK to anywhere in the body? Couple that with the fact that you seemingly hardly even have to aim at the body for a shot to hit. I just played 4 games on Moshpit and a sniper rifle was literally the only thing I died to apart from maybe 3-4 deaths. Maybe that's because it's such a scrub gun that 95% of the other team were using them? What the hell were the developers thinking?
there is a video on youtube explaining where each sniper rifle hit marker will often OHKO.
but in BLOPS!, i started getting pretty good with the bolt action, I can tell there is a sweet spot for moving targets but I havent mastered it yet. whenever I want to feel like a skilled sniper i will play BLOPS1. I suggest you do that too.
The DSR is above the waist OHK because everyone used to complain about how stupid it was that a 50cal round tore people in half. The Ballista has natural lightweight and is only OHK to upper chest and above (like previous COD snipers OHK zone).
If it's so easy please, I invite you to go 2.0+ with over 20 kills and 5 captures. I mean they take no skill, if I can do it most matches you can too.
Get it right, do it nice. If you make a mistake, you're gonna pay for it twice. If you need it... got to have it. Get yourself a shotgun and bring it back home
