Get rid of dodging in ARAM
It's All Random, All Mid.
Riot needs to start enforcing it.
Change the queue such that if a game lobby is disbanded, all 10 players are given the champ they had at the time of the dodge. No more incentive for players to circumvent the spirit of the game and screw over everyone else in the process. We've all stuck with champs that aren't our favorite, so it sucks that much more the odd time you DO get a great pick only to be returned to the queue because a player took his ball and went home after they didn't get what they wanted.
I'm sure a lot of people would be unhappy about that. Too bad. Why are you signing up to play a random champ and then back out if you didn't get a specific champ? You can always create a new account where you only unlock champs that you prefer in ARAM.
The reroll system was meant to give players SOME flexibility with their random champion.... what good did it do when I have to queue into 3-5 lobbies before a match is created? Poor game design that is abused by the majority of players because they can get away with it.
Do your job Riot.
