One way of doing it is to just know the map. Get to know what area has the most foot traffic and get to know at what elevation to keep your reticle so that people run right in front of it so you get a headshot. A second way to do it is have a Sniper with the perk "Final Round" Yeah, you can just toss two bullets aside and the third is a guaranteed kill with a body shot Another OP perk is the one with the All Seeing Eye inside a square that's description is "increases target acquisition" or something like that. This lets the Sniper Rifle gravitate to the head when aiming down sights But the biggest reason that so many people are good snipers is because of the Aim Assist. Now, Aim Assist is that thing where when you're looking at 1 enemy but another one runs across your screen and the game tracks that one even though you didn't move your controller. This basically upgrades someone's sniping skills in any other game by threefold Personally, I spent so much time Sniping in a game on PS3 called "DUST 514." In that game, you can't use the Right Analogue stick to aim. if you try to strafe while looking down sights the reticle goes crazy. same with forwards and backwards movements even while crouched. I've also played a ton of Planetside 2 on PS4 which is significantly easier to aim, but has bullet drop and constant scope sway. When you take the playstyle of Destiny in which you can freely move about in any and ZERO scope sway, Sniping in Destiny is way too easy.
