I confirm your feeling
last 30 games: 8 wins. 22 lost. As healer.
From silver 3, I fall down to bronze 2. I even had 10 lost game in a row.
Impossible to stop my falling. I go lower than my placement.
What Iāve seen (same as you)
- I played vs deranked people. Everyone have 20 kills, heās got 50 kills. Iām not kidding.
- I played vs cheaters. Widow with 3/4 headshot⦠then swith to junkrat.
- 1 Played with leaver each 5 games.
- My teammates are more stup*d than my chair each 3 games:
- your dps takes widow when you fight against sombra and tracer
- everybody forget the payload
- you have a non stop flow of players rush alone against 5 enemies.
- launch your ult to kill one people (maybe but a lot of junkrat knows what I mean) during a non critical moment
- In silver/bronze the main objective is ākillā. not the group, not the payload, not the point.
Iām able to adapt ( pick brigitte vs close fighters, play with position, etc) and still, you donāt see this gap in the other team.
There is not logical explanation. You cannot be bad suddenly from silver 3 to bronze 2. I admit that I do sh*t sometimes but I admit that the matchmaking doesnāt help 
As support, do you ever try to get out of bronze? 
Blizzard is unable to restore basic functionnality from Overwatch 1 like find group so pick up is a truly nightmare, I confirm that all is done to stay where you are, force you to be carried to go up. If you are good, for sure, you will be placed in GM, platinum, whatever. Iām not so good, I was gold before and I felt to bronze where Iām stuck.
You learn nothing with bronze people⦠you just adapt and pick their bad habits and you stay in bronze
Against deranked people, I have a suggestion: based on deranked people detected (so easy), permit to bronze to play in a Platinum, Master and GM game. It will be fair and so fun. Imagine, you will feel what we have in silver/bronze when a total stranger do a mess in your game. This will be the most interesting feature in this game.
For now, I will stop, this is the first game where Iām not able to progress and since OW2, unable to build a team to progress easily.
Restore the āfind groupā instead of Warcraft crossover. Oh wait, money first.
