Yeah after spending 3 weeks climbing from Seeker 1 to Alchemist 5 all I really noticed are longer queue time - now 3-4 min is fast, usually takes 5-7.
In addition to that they clearly made something with hero picks and priorities - probably something to do with that new priority token

(soon to be monetized) - so that I have not gotten my single top priority hero for like 10 games.
Will trick the system by putting all of them to low priority
Back to matchmaking topic - most of the games have been total roll-overs aka you lose badly at least 2 out of 3 lanes, by 10 min at least 2 people have 10-15 deaths and 0 contribution to a team. If you speak to them, they report you and you get muted for a week!
Sorry but what I started doing is just throwing hard these games and doing my best on ones that are 50/50 even though those are like 1 in 5 I would say = you lose badly 2, win easily 2 (in many games I don't even participate in team goals and see if it plays out 5v6 and it does = so bad is the difference in skill that we can win with me doing nothing for 10-15 min).
Valve you should do better than this, this is a joke not gonna lie.
Game is fun, but the fact that people learn how to play in Alchemist ranks or me testing legend builds in live game because we losing / winning by a mile... that is not fun, not how ranked should be. All I say - I might run out "fun" soon and quit, I need competition in a competitive shooter not just shiny effects and brainless teammates / opponents.
