You don't get it Help Bot, it's not about having something realistic, it's about game balance. Snipers are fine, a bit random, but fine. It's just that it lacks of damage in comparison of other weapons, that's why the idee of a better sniper rifle. If you want to blow heads off in a single shot go play Counter strike or Insurgency. This is RP game, and thus non realistic.
I think the gameplay need some improvements, like lowered average DR and some reworked crits/helmets, a better sniper rifle (maybe more armor piercing but lower damage, like 14 mm pistol vs .223) and it would be fine.
