Read my post again where i said
"Ballista scope in time 0.37 seconds
Average SMG time to kill 0.18 seconds "
I didn't compare the ADS time of the sniper with the ADS time of an SMG. I compared the ADS time of a sniper (i.e the time it takes to quick scope) with the "time to kill" of an SMG. This is the multiplcation of bullet damage and fire rate assuming you are on target. It's worth noting that the scorpion can actually kill in 0.16 seconds in close range!
Also, to those that cry about aim assist. This argument is irrelevant for three reasons.
1:Aim assist on snipers is removed from hipfire in this game (there is no longer an assist in lining up your shot) it is only present when scoped in.
2: ALL guns have aim assist on console anyway, but the other guns have hipfire aim assist aswell.
3: NO guns have aim assist on PC and the same arguments occur.
What do I mean by that? I mean that SMGs are just has over powered on PC as they are on console, and quick scoping is just as moaned about on PC as it is on console. WITH or WITHOUT aim assist. Therefore it's irrelevant.
Also you say:
"The One Shot One Kill with a QS has no draw backs once the initial slightly higher learning curve is mastered."
What about the massive drawback of missing your shot, or hitting a leg or not the upper chest and the resulting hitmarker giving the other guy three quarters of a mag to fill you with and you having no defense?
Also, FYI the KSG with quickdraw is a much easier quick scope option in close range than ANY sniper rifle in this game!
