So you're telling me that the Mercy who resses 2 people into 6 enemies 5 seconds after the first point on R66 defence is lost, instead of using it before so we could have actually held it, is just as good as me because she has the same rank as me? Or the stubborn [insert random dps hero here] who keep running in solo, so every team fight is essentially lost because it's 5v6 every time?
Just because Dunning Kruger effect is definitely a thing it doesn't apply in all scenarios. This is all at 3200-3400 by the way and no, I do not consider myself a Top500 player.
