Solo Rank

Why is it, we can get individual scores at the end of the match, but the points won or lost is based on if the team won or lost, this is just horrible. so many times i've tried to play nice, only to get the afk on my team EVERY promo game or the troll that didn't get mid as last pick.

How hard is it when we queue to select what roles we would like to play, and queue us with people who will play the other roles????????? Make it clear what role each player needs to play, that would be a real ranked system.
