Being a sniper user, the only problem I have is that sniper shots below the head only do around 50 damage. 

Here's why:

First, the most important detail is that sniper users only have 60 health, compared to at least 100 health in other classes. In order to compete at a higher level in the current meta, a sniper user's aim must be almost perfect. All players at a higher level crouch jump and maneuver so quickly that it is hard to hit their heads all the time. So naturally, hitting the opponent's body is going to happen more often than hitting their head. But when only around 50 damage is taken off with a body shot, the sniper user is forced to bring out their pistol; it takes 3 additional body shots or 2 headshots from a pistol/auto pistol to kill the opponent (of a 100 health class). While 2-3 shots may not seem like a lot, that's because it isn't. It only takes 2-3 shots from an assault rifle or submachine gun to take 60 health off an opponent. 

In conclusion:

Yes, snipers can easily win gun battles, but only if they hit their opponent's head with the first shot. If they hit their opponent's body for only 50 damage, there is a very high chance they will lose the battle because neither the rechamber speed of the sniper nor pulling out a pistol will be fast enough to beat a high-level sprayer. 

I am not saying that the sniper should be a one-shot kill to all parts of the body; I just think there should be an increase in body shot damage from roughly 50. I think 80 damage would be fair so it would take much less time to finish off an opponent, while other classes will still be able to easily kill sniper users due to a sniper's health disadvantage.

Sign this to give sniper users a chance to compete at high levels with all other classes instead of only giving them a chance if they hit headshots every time.
