RIOT, I AM SO MAD!!!

I demand to get my loss taken off my game.

I have been in Bronze 5 for forever and have gotten to the point where I need 2 wins to get into Bronze 4. But in the start up, when we were selecting champions, I say I'm going mid and select Vladimir but at the last second, someone else selects Yasuo and says they are going mid, then the thing closes. I did not want to lose this match or any match while I was in the line up. I'd have to start over again. So I decided to leave, for the benefit of me and my teammates. A hefty sacrifice, but I did not even play a game yet. How and why are you giving me such a thing as this.

If someone on your team (Riot) blindly went in your lane as a champion that cannot be played elsewhere and no one wants to change than wouldn't you too try and quit?

I want to get out of Bronze 5 and at least be in Bronze 4 but I can't do to some of the poor decisions that are made. There really needs to be a way out of the pre-game (champion select) screen with no penalties.
