Worse than just flamers who bitch about you if you're a noob is people that pretend they're pro and bitch at you for "feeding".
Picked Dark Lady and was going to pair with one of our two Str tanks, but they declined saying they were in Ventrilo. So, I'm in the lane with NH against Moon Queen and Blacksmith. I died twice in lane because of their ridiculous range. The rest of the game was them bitching about me feeding because every time we went to gank, the Str would refuse to initiate, Witch Hunter only KS, and NH was the only "pro". Fucking hell.
