Honestly it's all on which gun you're using. I was always a scrub at sniping (I thought it was too much like Halo, and I HATED Halo), but the Queenbreakers Bow helped me with my aim. I then started messing around with Shadow of Veils, and duuuuude it's a beast. I've even been getting a few quickscope headshots. Lol it restored my faith in sniping
