I dont play MP but i can see it being annoying there, so maybe not include it in that mode. But for singleplayer (which is the only reason i buy games) the answer is yes, im weird i guess Im not saying it must be the most realistic sniper sim ever, but i dont want to just aim dead center with my sniper and get an instant kill, its not satisfying (for me) Maybe add the option along with the difficulty modes, some kind of custom difficulty mode? It does mean a lot to me though to have realistic ballistics.
If you mean bullet drop and wind affects on gameplay over realistic sniping distances, then I'd hope not. While I used to think this would be cool, I don't think so anymore. Why? Precision shooting is an exacting science which requires months and years of training and practice to hone to consistent accuracy under a variety of conditions. Do you want to spend hundreds of hours in-game creating a DOPE sheet for every weapon and optic combination you might use, while _hoping_ your team in MP actually employs a sniper properly?
I didn't think so.
You'd be better served learning to shoot and move as a team.
I can see how the trailer gives that impression as it is so fast moving, with the vehicles etc, and the way it is cut, but the gameplay is not designed for run and gun. We need to see some good co-op gameplay footage.
