Dodging Queues
(Not sure if this is in the correct place.) There needs to be a much harsher punishment for dodging than a 15 minute wait. That's enough time to go grab a bite to eat, go the the bathroom, whatever. It's not really much of a punishment, and thus, wont (and hasn't) fixed the problem.
It is so annoying to have everything ready to go for a match, then have to restart an entire queue because someone decides they don't want to be in the round anymore.
Its an even bigger issue in ARAM, and there are a lot of people (including me) who prefer this game type over Normal matches. It is ridiculous when you've been getting terrible rolls all day, then you finally get a champion you're pretty good with, and someone decides they want to dodge. Its messed up. You should at least have the option of keeping you initial roll.
