There's a hidden mmr system the same as ranked for unranked games. You start at 3k mmr and move up or down.
At the moment due to having a very high win rate with 5-stacks it's hard for me to win in pubs.
Earlier this year (jan/feb) I was on a +70% win rate with stacks (though I play with 4 different teams) which fucked the shit out of my mmr. When I started playing with certain less skilled teams we would lose every time because I would be dragging the party up so far. At the moment it seems to have stabilized.
I haven't had any new players for a long time.
Btw if you want to find your mmr for unranked, look at the ranked mmr for players you play with/against in pubs and it will be roughly similar.
EDIT: IO tether teleport exploit was patched out
