Mathc making system suck


Most of the games i play on faceit, i get matched in matches where i win 40-50 eLO and lose 1-10 elo.
These types of matches is something i get often and is so fucking stupid.
Majority of these games are free loss. My teammates sees thie elo diffrence, and they dont even try. give up etc.
Why do i get majority of my matches like this?
