It is interesting how some players think that matchmaker is their enemy and how it is giving them rigged games and how is matchmaker handicapping you on purpose. I will use two examples to explain some things.
1. Theory/Myth
I am important and matchmaker is creating games for me to force my winrate closer to 50%. Matchmaker is handicapping me because I am good so its giving me bad team mates if I win games.
2. Reality
I am random person amongst thousands of others and I am just number for matchmaker to fill me in team with same average MMR as enemy team.
So why some players think that 2. Is the case? I think it has two main reasons. Players do want to feel special. They dont want to accept that they are just random number for the system. They want to be something more, they think they are more than random number and matchmaker is acting in certain way because they are important/special. Second main reason is pride, feel of flawlessness, perfection. They do not believe they are the reason why they dont climb. Finding true reasons why you are not climbing might be time consuming and way to improvement is hard. You have to be open to criticism, invest a lot of time to improve. It is the hard way. Matchmaker is rigging my games, wow how easy that was it right? Yes it is easy way to avoid the hard way and blame the system. It is system, not me because I am good. Easy path, but not path leading to truth and selfimprovement.
Matchmaker is handicapping me!
Why would matchmaker do that? To keep you lower than you belong? Why? You may be highest player in match with skill just like you can be the lowest. Some think that matchmaker will give you potato team mates when you are playing too good. But what does that mean? Matchmaker is trying to make games 50/50 so both team have same average MMR if it is possible with current live player base in your elo. So if you are the best and rest of the team is potatoes, enemy team has the same. Enemy team have same average MMR as your team. If matchmaker is trying to handicap you, your potato team mates were place into your games why? So they have better chance to win with you? In that case, match is in reality fair as matchmaker dont want them to lose. If they were placed to your team so they can lose as they are intentified as players to drop, why place you on the team if you play good for your elo? Rigging games doesnt make sense either way. Competitive is not just you, its 12 players, two teams, you cant just say system is doing something to just you as there is another 11 players involved in the match.
Now, do you sometimes feel handicapped by your team mates? I think everyone do feel that sometimes. I do too, some players are just bad and will make your chance to win harder. Thats the reality. Not every 2300 players in pool will play the same. Several players with same MMR might provide different performance considering huge number of factors. Same skill for matchmaker, different skill in match. Your team mates will be inconsistent so in order to climb, it has to be you who will be consistent and trying to provide more value than you are expected if you want to climb. Its not enough to beat players at you elo, you have to beat players better than your elo to take their place.
Final words
Dont lie to yourself, stop blaming matchmaker for your fate and rank. Only you can change it. Its ok to blame the matchmaker or team mates from time to time in individual games to let off some steam, but in the end you have to realize that it is you in bigger picture. Your place in the system is reflection of how you play. You are not special case, victim of the system. You are just gold ranked(or any other rank) fish in the pond amongst thousands of others with same MMR randomly picked by the matchmaker to create balanced teams.
You are not expected to carry bad players, you are expected to do more than you should be doing at your elo. If you are plat and matchmaker will give you silver team mate, you are not supposed to carry him. You are supposed to carry yourself. Provide value as plat player or more if you want to climb. Just like silver player is expected to provide more value than silver player if he wants to climb provided value from all 6 players will make the outcome, some games cannot be carried, and some cannot ve lost as the value provided from players migh differ. Thats why it is important to be consistent. And dont expect plat play from silver player. He is not expecting masters play from you either. I know its hard as I sometime do same mistake.
Thats all I wanted to share this morning
Good luck with changing the mindset and maybe climb something
