Just to be clear; I'm not talking about the type of situations on the front page right now where they lose one fight and call game over.

I'm talking about the situations where three of my team have just died, the opposing team is 4 levels higher and never strays more than 3 feet from each other, and they are now slowly approaching the core backed up by 3 merc camps and a boss.

At the point where there is quite literally nothing I can do, but I still have to wait about 30 seconds before we officially lose; how do I stop myself from tilting out of my mind?

(And this is a situation that happens all the time for me. There is a reason I spend about 80% of my quick-matches in leavers queue, and by extension the reason I will not touch competitive because I will never be able to make it to the end of the game.)
