@B Monkee even if your last ban was a whole year ago, leaverbuster doesn't reset based on time, but the number of incident-free games between punishable offenses, I had to play 100 games consecutively without incident before I was allowed leniency on my next offense where I DCed because of internet. As far as i know, the wait times for low priority queue will never be decreased no matter how many games you play incident free. The leaverbuster system is fair, and even though i got irritated with it too (since i did get a 20 minute wait at one point) i earned that wait because i continued to try and play at times when i knew my internet was not stable and it cost other players the game several times. If you are ready to quit league because it is boring then fine, but don't try and say it is the leaverbuster system, because it isn't. You just don't want to be punished for ruining other people's games.
@Xydem the remake punishment is not instant even for a first offense, if that did happen to you you might want to consider contacting riot support and figure out what happened. Just make sure you aren't forgetting any games where you might have been afk, even if you returned to the game, and like I said to B Monkee, if you returned to playing the game after a long time, know that leaverbuster doesn't return to a lenient state with you based on how long between offenses, it is based on the number of incident-free games between offenses.
But it is definitely unfair if you happened to get a low priority queue after a single remake if you have not had any offenses in the past.
@Jungler Pjevsen like zombiemaster said you had to have had a large amount of offenses before you ever got a 20 minute wait time in the first place. It sucks that your dog ended up getting tangled in wires, but if you had been more careful about when you played in the past and not committed punishable offenses then this punishment you received would never have happened. And honestly, I don't mean to bash on Riot, but even the 20 minute queue is nothing but a joke. The only time it really has any effect is if you are trying to play with friends, but even when I got it my friends were willing to wait for me (although i did feel like shit making them wait so i tried to play on my own when i got leaverbuster). Just try not to play at times when you know you are at a greater risk of having to leave the game whether that be from latency (lag), parents, or dogs getting themselves caught in wires (although i swear those little sits do everything they can to mess your games, my dog pulled out my power cord once). After you play enough games without any offenses you will be given some leniency again. Until then the game kinda fcks you even if you have every intention of doing that right thing, but you gotta just tough through it.
