If you want to put a scope on it make the dmg half or more what it is now.
Getting picked off from years away is NO ONE's idea of fun. It's annoying and gives the feeling of No chance.
It would make all other weapons worthless in comparison as most engagements happen in pretty open areas. It's bad enough as it is with no scope / the holo. I can get head shots no problem and thats insta death.
Play DayZ. You can get picked from years away and it's still fun. If you quit over getting picked off you're either A) the laziest person alive because you feel justified in quitting over one death. Sorry buttercup, put on your farmin pants and get back to it.
B) You're a terrible player and you feel entitled to survive 24/7 in a SURVIVAL GAME
C) You think the game will turn into a DayZ hillsnipe fest (which because of how easy it is to get the bolt action right now, it could turn into that... so when they reduce the potential of finding them to nearly impossible like they're going to do with all military weapons, it'll work better)
D) There's an issue within you in which you feel you shouldn't fear losing your items... Well, it's a survival game, AGAIN.
I hate to break this to you but honestly, I hillside snipe in DayZ all the time. It's fun. I win some, I lose some. But the nature of it is that you're not invulnerable. So as it stands, I'd like to see a scope since it would give it a more fluid feel for scouting areas as well. Just because you have a scope on it, doesn't mean it'll be accurate.
