Trolls, trolls everywhere

I'm angry.Today I was playing duoQ with diana.In our 3rd game we found a troll ^^.
first pick sivir and he banned fiddle and vlad, I said to diana "I'm afraid he will troll".
OK first 5mins he was afk and then he started to feed, just look at this..



have you ever met someone like this?

Always, bad example cuz he picked 2 times support but well, u can always find results like that.

if id get a troll in ranked just every 3rd game, i would be quite happy
