Alright, so this is a matchmaking example I suppose.
I am duo queuing with a buddy of mine. We are, at most 100 point in Elo different. I end up in a lobby with another duo queue on my team, and one random person. We get the typical annoying calling out of stuff, which I honestly do not care about as I feel at least comfortable in all roles. So 1st and 5th pick are together, and my buddy and I are 2nd and 4th pick. Pick and bans go fine. We have a top Mundo, and a jungle Irelia(5th pick) which is not optimal, but I have played with them before and they are usually alright. We are also on the Purple team, which usually indicates we are the higher overall Elo team(in matchmaking's Eyes at least).
We go into game. My buddy and I are bottom lane by happenstance, we didn't call anything out. We get invaded at level 1 at blue. Typical stuff. We all help our mid get away(well me and my buddy. Irelia stayed in the bush near blue). 30 seconds later. First blood from our mid. As soon as he dies. "Noob team" It just went down from there. I tried to stay positive for the first 25 minutes or so. In which time the Fizz(mid) repeatedly tells me to "STFU Janna". The top Lane Mundo gets obliterated between bad plays, and poor jungle ganks on our team, and good ones on theirs. We are pushed to our tower, which leads to a quadra gank about 14 minutes into the game.
This goes on for 35 minutes or so. The opposing Varus taunting our team(I had muted Fizz, Irelia, and Mundo at this point) talking how he is 1500 and this is a Smurf. We got outplayed. No doubt about it. The game ends. I lose 6 Elo, which clearly shows I was "supposed" to lose the game as I did not lose my typical 10-15 Elo. The Mundo had 1 ranked win , and this is just below 1000 ranking. Fizz has 26 Wins. Irelia has 36 wins.
Did the duo queue from the both of our groups inflate us to such a high level we get faced with people 225 Elo above our highest currently ranked player or something? The Fizz was not a great player, but I felt bad that he got sandwiched with 2 duo queued groups.(His attitude was also awful). I will admit, I did snap with 1 comment after the first 20 minutes or so, but after abuse for a while, you do lose it from time to time.
