Why do people have to troll?

I was in a ranked queue. 1st pick chooses Yi. 2nd/3rd pick is Thresh exh/flash & Heimer(mid) TP/flash, 4th/5th pick is Zed(now also calling mid) & 5th pick instant lockin of Braum exh/flash. Zed and Heimer say fuck it, both go mid, no top laner, tell Thresh to go adc and Braum support him.

It isn't fair that you're forced to deal with queue dodging when people like this play the game. I have to take a penalty because I'm not going to play with a team who is already fighting with themselves before the match even starts and leaving lanes completely open?
