LeaverBuster FAQ

What is LeaverBuster?

LeaverBuster is a system we have implemented in order to discourage Summoners from repeatedly leaving matches and/or idling during gameplay. Summoners who exhibit this behavior and have a trend of leaving/idling in games will be placed in a low priority queue.


Can you take me out of low priority queue?

No. We will not take your account out of low priority queue under any circumstances.


I just disconnected from two games! Am I going to get banned?

No, your account will not be banned. However, it is possible to be punished for leaving just 1-2 games. Players who leave games will be placed in a low priority queue and will be required to play 5 matchmade games without leaving before exiting low priority queue.

Note: Leaving ranked games is considered more severe than leaving normal games.


It is not my fault. My internet/your servers disconnected me. I had a real-life emergency. I had to get off the computer. The game crashed. Unban me!

We understand that players may be forced to leave from time to time so the system has been designed to keep these situations in mind. After leaving a few games, you will be placed into a low priority queue; as long as you can complete 5 matchmade games without leaving, you will be returned to the normal queue. However, if you continue to leave games, you will remain in the low priority queue.

Note: You are responsible for all activity that occurs on your account. Please review our guide on account security article and make sure your account is safe and secure. If you feel your account was compromised and that activity occurred without your knowing, please re-secure your account.


What can I do about my Leaver Level?

Make sure you can commit to upwards 40 minutes of uninterrupted play time before joining a match. If you find that you are having many instances of emergencies, disconnections, etc., please resolve these issues as best as you can.


If you are experiencing technical issues or the game is crashing/disconnecting...

Please see the following Support Article:

If you need further assistance, please contact us and provide us with as much information as possible(screenshots of any errors, etc.) and we will do our best to assist you. It is possible that we may be able to help you prevent this from happening in the future.


I crashed and got a leave/MMR loss. Can I get those removed from my account?

Our system does not allow the removal of leaves or the modification of MMR. It was designed in this manner in order to prevent corruption.


How long will I remain in the low priority queue?

You will be placed in the low priority queue for 5 games. If you continuously leave, the low priority queue timers increase from 5 minutes per game to 20 minutes per game.

Above is the pop-up visible while in the low priority queue. The amount of time will vary.


Are ranked, normal, and co-op games treated differently?

Ranked is treated much more severely than normal when it comes to leavers.


I left a custom/tutorial game and I got a warning that my account may be temporarily suspended? I thought custom games didn't count?

They don't. This message will appear every time you leave a game, but custom and tutorial games will not earn you a Leaver Level. LeaverBuster only applies to games you have to queue up for, such as Normal, Ranked, Co-Op Vs AI, Dominion, etc.


I'm a paying user. Shouldn't I get a bit of leniency on this?

No. Every Summoner contributes to their team's victory or defeat on the Fields of Justice. Those who repeatedly leave games or idle during gameplay hurt their team and the overall experience of all Summoners on the field. In order to discourage this behavior, we must take action against those who make it a habit.


What happens when I leave a game for the first time?

After the game, you will see a pop-up with a LeaverBuster warning. You must follow the prompt on screen in order to queue and play additional games.
