I don't want to sound like a broken record

But this matchmaking is extremely problematic. What is the rationale behind my entire team consisting of people who doing promos (and have never been ranked in previous seasons on these accounts) vs. mid gold and high silver players?

I tried to console the Jinx after the game cause I even told him that it was a complete mismatch. And from what I read on the boards this also happens in promos.
