Sniping used to be more skillful, therefore you never had 40 long range campers because it was hard to hit, let alone kill anyone, but that was back when there were more than 4 classes. With only 4 classes I can understand why the devs don't want one of those 4 to be out of reach to a lot of players. The problem the Devs have is they keep saying they are making a classic BF game yet keep changing the mechanics that made the BF games, well BF.
Because you had exaggerated gravitational effects and low muzzle velocity on the sniper rifles. Now, they are realistic, it still takes skill, even more so now since you can't see your shot only impact. Adapt, or Don't play.
