So wait, how did you determine how to deal with pre-made teams vs solos?
Some matchmaking pools avoid this completely by only allowing 5 man pre-mades vs 5 man pre-mades (ranked games, etc).
Others mix pre-mades and solos freely, and to be fair in these cases, we performed analysis on several hundreds of thousands of games to identify how much of a skill advantage this gives people. We found that a variety of factors influence how much of an advantage being a pre-made is, ranging from the size of the pre-made (i.e. 2,3,4,5 people), to the skills of the players involved, to combinations of pros and newbs, to other more subtle factors that must be used as well.
Having found these advantages, we know how much we need to boost your rating by in a team to make a fair match, and apply the appropriate, mathematically justified adjustment. These results in some cases are very surprising (while still appearing correct in the statistics)
While we will not give precise values because those are trade secrets, we can say that:
5-man pre-mades are only moderately stronger than solo queuers.
Partial pre-mades are only a little bit of an advantage.
Newbs don’t benefit much from being in a pre-made, while experts benefit a lot.
Teams with a high variance in strength tend to be stronger than those with low strength variance. This suggests that the carry effect is stronger than the feeder effect -- generally.
Okay, fine, but why do you even match pre-mades vs non-premades at all?
There are a few reasons for this:

There are a few reasons for this:
- It helps the system find your skill rating much faster, so that you get fair matches faster. This works because if you pre-make, it reduces the amount that “bad” or “good” luck related to your teammates causes you to win or lose games. If you pre-make, you join up with people of about your skill, and you now get less random teammates boosting you/screwing you, so your rating gets to an accurate value more quickly because more of each game result is due to you and your friend, who are close in skill.
- We want people to easily play with their friends because they will have more fun if they do, and you can’t have a 5v5 matchmaking pool of all 2 man teams, or all 3 man teams – you need a mixture for it to work. We chose to include 5-man because it’s a lot of fun – if we have large enough pools later, we might separate 5-man premades from the partial pre-mades – but the data we have shows that this won’t improve the fairness of matches much at all, it will be about the same.
