The ladder includes Solo, Random Team, Arranged Team (2vs2, 3vs3, 4vs4) and Free For All, giving a wide range in which a player can determine and choose which ladder best suits them.The current matchmaking system also prevents players with very positive records and very negative records from being able to find a game in a reasonably short time.
