It's my observation that sometimes when I lose against someone that is ranked far lower to me and especially if I lose multiple games in a row, then the que starts to take extra long to match me in a game.
I'm not saying that the game is trying to find someone of my low skill to play against, but it seems like a possibility. Many different games do all kinds of funny business with the matchmaking and I just ask that I'm matched quickly. As already mentioned, I'm already caused to play against players that cause me to lose 150 points the vast majority, like 90 % of the time. At the very least, if I'm going to get these matches that I don't want anyhow, can I please be matched quickly?
Don't tank
