Losing streaks in League of Legends

Riot Games didn't give the algorithm of their matchmaking system but they told their matchmaking system is based on elo/rating/mmr. If the waiting queue is long the teams will still be almost same rating but the players can change. In example:

Team A:
4 diamond
1 bronze

Team B:
5 plat

This case occurs usually in smaller servers but it may happen to you. Also when you're on a losing streak either you play bad yourself everyone else seems playing good or your teammates on their bad day and since the opponent is a bit fed they seem to look playing better.

Tilting is the main factor in loss streaks in League of Legends. When I was going through Silver and Bronze I experienced this regularly. Becoming mad at the game and at your team has great negative effects on your gameplay, causing you to blame others for your own mistakes and also avoid the foundations of tactics to win, like warding, missing calls, and positioning.

The best way I've found to avoid tilting is to just take a break, although I no longer play League. I'm into the CS: GO MM and tilting is also very present in that game; I usually play Skyrim in between games and even take an hour break to do other things non computer related to avoid tilting.

This answer is not about the MMR matchmaking but more about why you have winning or losing streaks.

In my experience, you will have winning streaks and losing streaks. The only thing is that when we win, we tend to tell ourselves that it's because we are good. When we lose, we subconsciously try to blame others or to minimize our part in it (you can always do something better).

But to be honest, sometimes you will win even without doing anything, being carried. Sometimes you will have to carry hard to win. It will depend.

I feel that at the end, the most important part is the sinergy with your team mates. So many times, I happened to win or crush a "good" composition with a "bad" composition just because everything goes well with your team mates, ganks have the perfect timing, people think about the same move beforehand and are synchronised etc...

Of course your skills, the level of your opponent is related to your victory rate, but you can't do much when there is no synergy in your team. You can just try to communicate more, without flaming. Try to do the best with what you have.

You are probably on tilt.

You lose games because you are still angry from the fact that you lost the last game. just take a 10-15minute break between each game not matter what the result was. this helped me a lot.

It seems like you play against much better players because they win... and you lose.

Does the LoL matchmaking system take the previous games results into account?

Yes it does. you have a hidden MMR which tries to help making balanced games.
