Fking Trolls

I just had to dodge a game because I was going to trade with this support. When she asked for Nami I told her that i didn't have her, and then she decided to go Irelia support and threatened to feed and then afk. I was going to pick Janna in order to still trade, but because she didn't communicate thereafter I hastily picked Garen(Don't judge, I had to do some quick thinking and I thought she was going Irelia support).

Seriously this needs to stop. I'm tried of losing lp because of trolls in champ select.
