Yes, when a player abandons a Rocket League match, the player who leaves early will experience a significant loss of Matchmaking Rating (MMR).
Understanding MMR Loss from Abandonment
Rocket League's matchmaking system is designed to penalize unsportsmanlike conduct, including abandoning a match prematurely. The system recognizes that leaving a match early is unfair to teammates and takes measures to discourage such behavior.
- Substantial MMR Loss: The player who is the first on a team to leave a match early will incur a more substantial MMR loss compared to the typical MMR deduction from losing a completed match. This severe penalty is a core component of the matchmaking system's efforts to maintain fair play.
- Additional Penalties: Beyond MMR loss, players who abandon matches also receive a Matchmaking Ban, preventing them from queuing for a certain period.
The developers are continuously working towards improving the matchmaking system to address and deter players from leaving matches early, reinforcing their commitment to a fair and competitive environment.
