troll champ select

As a low elo player like me you probably have been there a troll pick of one of your teamates in ranked. Now you only have two choices leave and lose 3 lp (more if you left already that day) or stay and face a certain loss. My idea is to have a report button in ranked champ select and when 3 or more report that player for troll picking he has to leave que.
