I think people are going afk / ragequit too much because the punishment is wack. Oh, a waiting queue. Just let me watch some youtube, wait for the time to be over and play.
I came up with this idea, all these restore after 3 months;
First time AFK on your account: no punishment. This is for people who have rare internet problems. Everyone can have them once in a long while.
Second time AFK on account: Warning screen and 10min waiting queue.
Three or four AFK: Unable to play matches for 24 hours. Double LP loss if Ranked.
5+ times AFK: Same as above + honor drop.
People tell me : but my internet is wack!! So that means 4 people have to suffer because for some reason you can't have normal internet/computer? If you have often lag/internet disconnection/pc freeze then you should accept League isn't for you, or fix it.
