How was your day today? - DotA 2 Edition

I'm starting to hate playing with randoms. Some moron spends the whole game bitching about everything, he gets killed at least 3 times while he types and keeps bitching because somehow loosing the game it's everyone but his fault. I suck, everyone made mistakes, I'm sure everyone tried their best but all we get is whining from one guy who thinks played perfectly. It's just hard to enjoy the game that way, but I think that if I only play with SPers I won't ever improve if Dusk and Adam carry me every match. -_-
/frustrated.
