Oh my god, you actually have to snipe now, instead of abusing auto-aim and bullet magnetism.
Snipers (or DRMs) are not supposed to be up close. They are supposed to be in the back, annoying and picking off troublesome enemies. They're not supposed to have the highest kills, or the most score.
When you pick a sniper rifle, you are making an active decision to take a weapon suited for a certain purpose and role. Its not the weapon's fault that it doesn't what your twisted imagining of it is.
If someone gets up on you while you have a sniper, either hope your secondary or team can save you; because sniper rifles aren't supposed to, or even going to work at close range.
To put it more bluntly; if someone gets close enough to you where you are in danger of being shot or need to quickscope, you just failed as a sniper and deserve whatever fate is coming.
If you want to be up close, don't be a dumbass; bring an SMG, AR or Shotgun with you.
