The sad fact of the matter is that snipers are only useful if they don't see you, or are far enough away that only a high zoom scope can allow you to get a headshot on a moving target, otherwise, flinch makes the basically useless. Snipers are supposed to reward precision kills at a distance, regardless of whether or not you're spotted. I've been flinched by auto rifles to the point where my sniper was useless, at optimum sniper ranges. Something needs to change, that's the bottom line.
