The aiming might be harder, but the positioning involved with sniper in pants-on-head easy. All you have to do is know the best fire lanes and have your teammates feed you info on enemy position and movement. Saying that it takes more skill is just false. To the snipers that can ADS and come up with headshots, I commend them. But they are few and far in between. Most snipers are sitting somewhere with their reticle at head-level in a high traffic area and then pulling the trigger when a someone walks into it. That isn't hard... and with high aim assist, the game auto-corrects the small error that would otherwise result in small misses. IMO, it's just as hard to use a shotgun because you have to position well, ADS, and evade enemy countermeasures. Especially because there are players like me who thrive on playing protection for their teammates and shutting down rushes. In the casual crucible... shotguns do decent, especially in object formats that force close quarters movement. But that isn't the level of skill that the game should be balanced to. At the competitive level, Sniper rifles are by far the most powerful secondary weapons.
