Matchmaking



Matchmaking is the process through which the system groups players into opposing teams for public games.

Ratings
All matchmaking is based on a hidden player rating similar to the Elo system. Theoretically, players of roughly equal skill will be placed in the same game. Partying with higher or lower ranked teammates may skew this calculation in unknown ways.

Find a match
This function matches the player with or against random teams and solo players.

Find a match solo
This function matches the player with other random solo players only.

Find a team match
This function matches your team against another random team. You must be in a team to queue for this function.

Find a co-op bot match
This function matches you or your team against AI-controlled bots. If you are queuing solo, the system will select your teammates based on similar skill ranking.

Find a compendium match
This function matches you or your team with random players to replay certain matches of The International. (Compendium owners only)

Settings
Settings allow players to be matched only with others who have selected the same settings. Selecting more settings can significantly reduce wait time, as the system will be able to search for compatible players from a larger population pool.

Priority
Priority is a status that determines how quickly the system will match you with other players. All players start at Normal priority by default.

Low Priority
Low priority is a penalty administered when:


 * A player has abandoned too many games.
 * A player has failed to "Accept" ready games multiple times.
 * A player has been reported multiple times.

Players in low priority will:
 * Have extremely long queue times.
 * Not receive any item drops or Battle Points.
 * Cause all players in the his/her party to enter low priority until they leave the party.

Low priority cannot be removed. A countdown in the main menu will indicate the time remaining until low priority is lifted.

High Priority
High priority is granted when:
 * A player is returned to queue after a recently failed matchmaking attempt.

Players in high priority will:
 * Have much shorter queue times.
