I think the constant stress is an insight into how thought patterns change when in competitive scenarios as people degenerate into racists and/or sexists who want everything around them to die, lol, there should be way more studies on it.

Oh, I know that winning is hard when your mmr is so high you're placed with four deadweights vs 5 semi-competent players, I was speaking more to the fact that they themselves still perform about as good as one can expect given the scenarios thrown at them.

I guess I should clarify that my definition of pro is more narrow because I view a lot of pro players as very mediocre.
