An idea for ranked dodges
There should be an active set of "trigger terms" so that when you enter a champ select and somebody says "mid of feed" or "afk" it could recognize that and send a vote to the chat, 3/5 votes dodges the champ select and the player who activated the trigger receives a warning. When the player is warned 3 times, they get a ranked game restriction(5-10 games of normals or more)
This will make it fair to everybody and it will lessen the feeling of having to sit in a game for 20 minutes with a player that wants you to lose. Just a thought, i dont think it would be too hard to implement.
