Question about matchmaking on Faceit

Is this true?

in soloQ better players get matched with worse players to balance out the team’s performance?
Im not meaning the “average elo” .
i think more about KD, win% and such in the past games.
Do these variables play a role in matchmaking or is it random and only average elo plays a role.

Average elo!

This is not ESEA where wins, kd etc. matters.

So, its just placebo that i think i get teammates who lost lots of games lately while ive won many?
