Every weapon has a strength and weakness. SMG is good at short range, but weak at long range. Sniper rifles are the opposite.
Getting one shot with no chance to react is annoying and overpowered.
So....shotguns should be overpowered, but not sniper rifles? This logic is why game developers fail time and time again. In no world does a shotgun slug penetrate body armor at 10 feet, but a .300 win mag with a tungsten core round does not. The XM2010 ESR shoots a .300 win mag irl just like they say it does in the game, and it will literally put a hole through bulletproof glass, but it doesn't one shot from any distance unless it's a headshot. That is terrible development regardless of what argument you decide to cook up.
