So he expects a player who never did it before to get it right the first time, despite being warned so.

And then erupts on a very agressive tirade. On the first fail.

Why do people expect others who never did some content to get it perfectly on the first try just because they did? Hell, why even throw the newbie in such an important role? Really?

Okay so this strategy works for a pickup group, that's awesome. But this man somehow expects people to, despite not even being vaguely aware of who eachother is, have perfect synchrony with eachother. And then proceeds to be angry when it expectedly fails.

I'm thankful for this strategy, but you guys need to learn to chill. You don't have the right to demand a perfect execution out of people in a game before the third try.
