I think it needs to be a ranked system. You get put with teammates around your skill level, and play against enemies around your skill level. Only time I went flawless was when I was with a group of random people off LFG, which might as well just be matchmaking, since I don't have a set group to run with. People may not get a great group sometimes, maybe someone left or wasn't very good, and that could be an issue, but the same thing goes for LFG. I've had some really good and really bad players come from the forums, and I've played with some really good and really bad players in matchmaking activities, and I'd say the same has probably happened for everyone else. If we can all complete all of these activities with people we didn't even know existed before that activity, I don't see why optional matchmaking can't be in every end-game activity.

TLW doesn't 1-shot, the shots are just fired too fast for your console to register. (Google "packet loss".)

Osciris?

This post was a short one with a lot of content.. 1: Matching the same people: It has happened to me and my team as well, but it only happened to us when we went out of matching. Then again, they might have not left the matching. 2: Four maps? Did it happen once on every week? 3: Remove which loss? I really doubt they're going to start removing losses from individual players because they played the same teams several times. 4: The enemy team did not leave? What's that supposed to mean? 5: As far as I can tell, Last Word does not one shot you, it does however have an extremely short kill time if you can use it properly.
