I know how match making works in ranked -- you are placed depending on how well you did overall in your previous match. In normals, if your team has a premade the enemy team will have a higher average MMR. However, I am not sure how this system works on the Twisted Treeline map. Is there a way to avoid getting into games with premades if there is a set way players are matched?
TT has its own map MMR but it works the same as in other queues. You basically have a "hidden elo" based on your win/loss ration of games played on the TT map and you are going to get machted with people who have roughly the same MMR. Also if you play with 3 Premades your opponents will be full premade aswell.
If you only play with 2 people two things can happen:
- You also get an enemy team who has 2 pre - 1 solo. Those will have about the same TT MMR as you
- You get 3 solo players who have a higher MMR than you (this is similar to playing with four premades in 5v5 while there are 3 or less in the enemy team).
The MMR is calculated with the Elo ranking system but it's not visible to other players.
