Since there are only DMRs in the game and not specific sniper-rifles, I would not expect to have very long ranged weapons in the game, but more accurate and slower firing assault rifles. Would also make sense, since we don't really have one-shot-kills. But the last official statement we have, that they are still balancing the range of the "long-range-weapons", so we don't really know, how far you can actually shoot.
I personally hope they include a few bolt-action rifles in the game, just classified as "DMRs". There are tons of players who LOVE to Snipe, and even though sniping isn't my preferred combat strat, I would be disappointed if there weren't any legitimate Sniper Rifles other than semi-automatics/battle rifles.
I'd honestly be surprised if bolt action rifles are added to the game, they seem to be adamant about forcing people to get up close, but I hope that they do.
I like having options, I like fighting up close with high RoF weapons/Shotguns but also being able to switch to a sniper rifle to cover a teammate and force enemies into cover while they flank.
