So I'm mainly a PvE player, but dabble in Crucible every now and again. One thing I can't figure out about sniper rifles is this... When I'm scoping in on someone who is shooting at me my crosshairs jump all over the place. Making it extremely hard to get even a body shot, much less a head shot. Now when I'm laying lead down range at an opposing sniper with either a scout, pulse, or full auto rifle I get domed instantly. I can be unloading a high RoF auto in a guy a mid range and Bam! he head shots me with a sniper. What am I missing? Thanks...
