Matchmaking broke for good this season?

I was having pretty good fun last season in both QM (65:36 on Greymane, slightly lower on Sonya and Rehgar) and ranked (35:15 on Tychus, slightly lower on Raynor and Sonya). The matches became a lot worse when latest season started, and just winning half the matches with any hero was a tall order. I decided to take a break and when I returned this weekend my team was losing 7-8 out of 10 matches, usually because somebody was either AFK or obviously feeding - this was happening both in QM and ranked. I played some 30 matches now and the trend stays the same, with some 10-minute matches against premades thrown in for extra fun.

Is there any chance to retune matchmaking to prioritize balanced teams over quick searches? I don’t care if I have to wait 5 minutes for a match to start - I can grab a snack or something. It would be way better than to get a match in 40 seconds just to again get demolished. As it is I will probably have to just say farewell to the game.

Who are these players feeding? Lol
Are they ever going to run out of food? and is the person they are feeding every going to die from eating too much of their food?
