AFK/DC on my team

I am currently playing my placement matches for ranked. I was Gold 5 for season 4 and my placement record is 2 wins and 4 losses. 2 of my losses were because of one player on my team got disconnected at the beginning of the game. It is honestly not fair for 4 other players in that team. It is possible to win a 4v5 game but most likely the team with one less player will lose. I really think that for the team that has a disconnected player in ranked should get loss prevented. It really is not fair, we did not choose to have someone who will get disconnected. So please Riot, consider this message and please do something about it because now my placement matches are all messed up. Maybe I could have 4 wins and 2 losses. It is really not fair... Please help fellow league player RITO!!
