I have never been banned or intentionally left a game but my waiting queue has jumped from around 2 minutes to around 14 minutes. I don't know what happened or how to fix it, I am fairly new to league and want to play better quickly but waiting 14 minutes for a 40 minute game to start does add up. Any advice would be appreciated! Thanks
Stop afking or leaving matches and once you serve your LPQ sentence it will go away.
If you really have such a huge problem with your connection that you can't stop, then stick to custom matches where I think Leaverbuster does not apply.
That's not low priority queue if your queue is just long. Low pri queue forces you to wait a certain amount of time before even entering the queue. Most likely it's because their aren't a lot of players around your level queuing for the mode you are at that time. Try a different mode or playing at a different time where there will be more people.
If you really are in low priority queue you have to work off a certain number of matches without leaving.
