It also counts as a "dodge" if you can't figure out a champ to click on. Its not just people who dont want to play those champs, its sometimes the people who are playing it for the first time and dont know who to pick. That happened a few times in my Q's then it happened to me because I hurp durped. Either way they still get punished and Im assuming out of the pool for the summoner icon.
Like it literally puts them on a 15 min Q ban the first time, 2nd time 2 HOURS. After that Im not sure but if everyone is seeing so many Q dodgers its probably not the same ones because everyones being weeded out relentlessly.
