Battleground Queue cancelers

seriously there needs to be stricter penalties for those who queue for battlegrounds and either cancel the queue in order to prevent the bg match and those who always wait till the last second to start them, both of those actions are RUINING the aspect of the game thats arguable the best part. being able to queue and cancel queue every 30 seconds is BULL!&%$@%^$#! please please do something about those types of people
