Sniper rifles in most games. They're the only gun that kills in 1 hit at all ranges, close range? 1 hit, medium range? still one hit, long range 1 hit. So for all of us non-sniper rifle users who chose an assault rifle that's balanced to kill in a certain amount of bullets with different firing rates and damage, snipers get to do it at all ranges? No.
To drive my example in more, I was using a shotgun in bad company and I ran in (spas shotgun, magnum ammo) , shot a sniper he survived my shot and killed me with his sniper rifle in one shot. That's BULLSHIT, there is no defending that at all, it's unbalanced and stupid.
At close range sniper rifles should do minimum damage unless it's a headshot, for those who've yelled at me that snipers need to be able to defend themselves at close range, pull out your backup pistol and use that.
When you go shotgun you have to watch people run by all the time who're out of range, as a sniper you should have to hide as well when someone gets too close. You don't get to be an all range fighter.
And don't give me it takes skill to do quick scoping, it doesn't. It's an exploit.
And that's it, sniper rifles in 99% of games are OP.
