The sniper can 1 shot 5 classes out of the 9 without charging tho
true but the medic can overheal all these classes and all the low health classes excluding medic have a sort of countermeasure
scout is really fast and mobile
spy can turn invisible
sniper can uh, one shot the other sniper
engineer has buildings to hide behind
medic is forgeted rip
in overwatch if you're not rooty tooty teleport and shooty tracer assface you're not gonna dodge for stuff
