I dodged queue yesterday while I was in a premade with my friend so I ended up with a 1 hour suspension. I'll explain why:
We pick the usual standard bans and we all agree on our positions (we would be premade bot) everything goes well, until the person who goes mid does something ridiculous, he instalocks cho'gath and says mid. Me and my premade are sitting on skype furious at what he is doing, continuing to call us all noobs and stating that cho'gath CAN go mid which, he might but he isn't as good as a veigar on their team. As a result I had to leave the game because I knew I would lose and my elo would drop and I ended up with a 1 hour suspension. I mean really, they should change the suspensions to be less harsh if people know their team composition is awful.
