Maybe you should spend less time picking your nose then and more time microing
Putting the game time to 90 mins is ridiculous for many reason I cannot be bothered to write because you should be able to figure them out yourself.
I've only quit out of two games one in which I mentioned the fact that the teams were completely unbalanced and there really was no point in playing and a game of combat mod that seems to be very popular, but completely dull. Buy tanks and sit back yay!
But whether you play 60 or 90 min games that is the reason people quit games once one side gets trenched in and the other side have has spent 15 mins and tons of points banging their heads against the "wall" what is the point to sit around getting killed for the next 25mins.
