Queue dodging
I'm all for stricter punishments for queue dodging. And let me say, I have literally never, ever, EVER dodged a queue. I literally have an icon for NOT dodging games. I don't care if there's a troll pick. I don't care if someone is being an ass in lobby. What I hate is when I have a limited time to play, and I spend 15-20 minutes just trying to get INTO a game.
I absolutely hate sitting in queue, get into the game, we all pick our team and begin to make a plan, maybe edit a rune page. Literally the FINAL COUNTDOWN before the match starts.... and then someone queue dodges. So then it's back into queue. Get a new match. Go through it all over again. Last 8 seconds before match load begins. Aaaaand someone dodges. Go through it again. Pick all champs. Last 5 seconds. Dodges. LETS TRY AGAIN. Aaaaaaand this time I don't get the role I wanted(or my champ gets stolen) so I just sat through 15 minutes of queue bullshit to get a role and a champ I didn't want to play. It's extremely unrewarding for people who DON'T dodge, and there is like not even a slap on the wrist for those that do. Oh, a 5 min queue penalty? I literally sat in that waiting for another match to get lined up, and sat through more dodgers.
And I hate it when "troll picks" are a reason for queue dodging. Back in S2, Fiddlesticks was considered a "troll" support, yet here we are in S9, he's a "support", and if you pick him for jungle(like he was in S2) people assume you're trolling.
