Hero League begins with a series of 10 placement matches, to determine initial rank. The more Hero League games are played, the more accurate matchmaking will become. Everyone will start their Hero League journey with a blank slate in terms of MMR, which may initially cause Hero League matchmaking to feel a little wild while the matchmaker learns more about each player’s individual skill level. This is an individual rating, meaning that it is unique to each player's own performance, and will not change based on different parties or players they buddy up with. The matchmaker will search the Hero League queue in order to place players with and against players of similar skill, and will also use a matchmaking rating (MMR) that’s separate from Quick Match rating. Players must queue for Hero League alone.
