Ranked just as toxic and as much trolls as normal

I was helping to camp Trundle top and got him 2 kills while he went back to base, i help him push out the lane. He then blame me for taking his cs and got ganked while i was away doing farming in my jungle as fiddlestick. He even threaten to go afk. Plus I also had a brain dead adc who just walk towards enemy team and die instead of running away from a safe area. Honestly these trolls should just stay at normal if they think they wanna ruined other players's game.
