@Meddler @Kidronnie Question about DQ

I don' t want to uncover too many technical things, but how is handled matchmaking between two teams of players where one has a premade and one has not?

Consider this example: pick two teams composed by solo quequed players completely identical in skill. It should be supposed that in certain circumstance both teams have a perfect 50% chance of winning. In this case, how the system would handle one team if said team had a premade of x players? It would still matchmade them against each other or it is more probable that it matches it with another team with an higher median skill, or against a team with the same median skill but with the same value of a premade?

Basically - the system takes in account the artifical increment of ranking skill with premades, counting it as a "social skill"?
