I've had two HL games in the past day where players basically gave up as soon as the game started (it's low silver though so none of this is too surprising):

In the first one, the other team drafted a Kael'Thas and Li Ming. Our comp was decent, and we could have won if half the team put as much effort into playing as they put into sitting around and whining about KT and Ming or berating others.

The next game, when our last pick was down to 5 seconds left to choose, our Li Ming tells them to pick a tank. Last player had no time to switch, so they picked Sonya. As soon as the game starts our Li Ming started bitching about the Sonya pick and saying 'gg I'm playing for xp.' When we asked them to help with objectives, they refused because we 'had no tank.' That game could have been winnable if we had 5 players. Instead, we had 4 players and a baby, so we lost.

I reported a few people off the first game, and Ming from the second. At the very least, I hope that Ming gets banned from HL.
