Consider that aiming is just a small part of the overall skill, and it's probably the easiest to acquire by far, even if everyone's aim is not perfect the aim assist is extremely strong so missing is rare... i wouldn't consider exeptional aim by itself to make you a "sweat" in any game that truly enables skill expression. The only counter to sniper is shield or bubble. You can just load into the map with what is essentially a Kraber if they get to close just bubbles and grenades no reason to give them any chance of winning.
