Because in a CSS setting the gun is an unbalanced pile of crap? A single bullet that just needs to hit you and bang, you're sat out for the rest of the match, its not like an AK that actually needs a headshot. Would be like BF3 getting an automatic gun that can 1 hit kill everything with a 12x scope. It would be in the game right? Therefore its good.
I was referring to you calling people noobs for using it, because they aren't.
But yes it would be exactly like bf3 getting an automatic gun which Is one hot kill and 12x scope, might aswell throw in no recoil.
Also there is no game that isn't unbalanced in many ways, and if it's that unbalanced why don't you just see 5 people with awps on each team in matches. (yes people do it in pub but a high percentage of people are there for the KD.)
