Ranked Ridiculousness

My main picks for ranked are bot and mid....how in the world was i given JG???? So now i have to be penalized for leaving the match because no one wants the role. I don't think that I should be a penalized for not knowing a role that i did not choose. [slayer-jinx-unamused] There should be a feature that tells you what role you got before going into character selection, that way if this happens again i can opt out of the match and not be hurt by it or hurt the other players.
