What is low priority queue and why would you be sent there?
How do you know if you're in low priority queue? What is average queue time?
Been playing this game since S2, and haven't the slightest clue as to what it is.
Can someone explain this to me or at least give me link that has a full explanation.
Papas rod2 votesIt's basically a way to stop afking/griefing games. When you afk in more then 2/3 games in the past 10 you will probally get this.
When in a low priority queue you have to wait 10 games 20 -> 40 -> etc minutes before going in to the "real" queue. Times will stack up depending on how many times you have it in a period of 2~3 weeks. For example you afk'd in a few matches and got a low priority queue, you finish it after the 10 games of waiting and then afk some games after that you'r probally left with a 40 min low priority queue. Meaning you have to wait 40 min before joining a game
.
Hope this explained it a bit
