Pregame Lobby behavior.

I just wanted to throw out an idea, see the response. Has anyone thought of creating a report option in pregame lobby because players constantly give up and troll before the game even started. For example today we had a top laner pick ornn so because the "bottom" picker didn't like the new champion and said that ornn is a troll, he then threw the game before it even started by picking xin zhao adc. This is obviously a terrible idea and can be fun to do in normals but like many others I take ranked seriously. This resulted in me dodging the game and losing LP but I can't dodge all the time with timer penalties. I have to do this so often(once or twice a day) it'd be nice to at least report him. Then again, that option could be very abused in pregame lobbies. This crap happens all the time... so share your thoughts!
