Issues with 4v5s in Ranked Solo Queue

I've had the misfortune of having 3 out of my last 5 ranked solo queue games being 4v5, with me being on the team with 4 from start to finish. The 5th person on my team never joined, even when one game went for over 40 minutes. I don't know the win/loss percents in such situations, but I do know that in a game fundamentally built upon teams of 5 players going against one another, being down a whole player the entire game is a massive disadvantage. Those games are not completely impossible to win, but are nigh unto it. I have been browsing the boards in regards to this issue, and would like to voice my own opinion that something does need to be done to rectify this issue. It is inherently unfair to penalize a person for something they have absolutely no control over, yet that is exactly what happens in the current system. Possible fixes have been mentioned on the boards, and I would be lying if I thought I had a better idea than what they have already come up with, such as the "mercy" option from the enemy team that I like the idea of. In any case, something needs to be done to fix the problem with 4v5s .
