I would be able to bear longer waiting times if that meant the games were more balanced rather than a bunch of stomps. People who have short attention spans and want there games 'now' are also usually the ones who quit early if things look even a bit bad in random games.
It seems ladder climbing at the 1-30 area is more about dodging these teams than actually trying to beat them with another random.
7-12 PM PST is when you can avoid the good AT's and get randoms most of the time btw.
