First of all, I’m not here to brag. I want to tell my story and maybe someone will see my post and got an idea to change/improve the 1v1 mm.
Yesterday I gave it a try to 1v1 after 6 years of pause. I thought it must have changed after these many years. They improved, I said to myself.
I remember the ladder as if it was yesterday. For me, it was really hard to beat Bronze 1. It felt like I was in a different league (maybe wood).
What I did to improve:
- watch online tournaments (I did it for years)
- watch live streaming and tutorials from pro players (like BeastyQt and others)
Yesterday I played 28 games, from which:
- 2 instaleave
- 2 wins (players were way worst than me)
- all the other games had big imbalance imho: I played against Dia, Plat and Gold almost constantly. Only a few games were against Silver.
After yesterday, I thought that today will be the big day. No more imba mm. I played again. Guess the league. It was Plat. 
Do I need to play hundred of games to have the opponent in the same league? I don’t think I can play hundred of loss games.
What am I missing?
