no exponential cooldown for dodging a queue

i do not understand this feature (if you'd like to call it that) of this game, 5 mins is understandable, but making myself and others wait 15 or more minutes to join a game is frankly outrageous. More often than not the people who dodge these queues are doing so to prevent a toxic or dis-satisfying experience for everyone, whether it be they didn't get the lane they wanted or someone else made it clear they were going to be toxic to the game, simply disbanding should be an easy enough solution, and often the better of two evils. league of legends seems to have a focus on punishing and reprimanding it players for often frivolous deeds, rather than just make it easier to avoid playing with those players. perhaps a stronger focus on rewarding those of us adjusting around leavers, poor communicators. perhaps develop a way of entering games in progress in which a player has left, giving them a scaled lvl/gold on start
