Matchmaking grievances

Is it just placement matches people get into any queue? I’m onyx in blitz 2v2 and it puts me with level 1-10 partners when I solo queue. What??

I´m experiencing quite the same issue. Although my case is set in a very different Rankrange…
When I´m playing Standard 2v2 i get Partners from Level 1-10 all the time and my oponents are usually both 30+.
I´m currently playced in Platin 2 or 1… don´t know if thats high but ist a bit odd if you ask me.
