Leaver Buster is TOO punitive!

I have been playing this game from the very beginning and have seen many trends that were positive and negative. One negative has always been people leaving games. The team ends up short-handed and usually loses. This negatively impacts the game play for many. Most can agree that rage-quitters and trolls need to be weeded out. But what of the player who experiences a power-outage, internet failure, or game/computer crash and disconnects from the game but returns post haste? A 20 minute wait time in a lower priority queue for five games is answer Riot came up with? Given the number of years I have been playing this game, I feel rather betrayed. I experienced a power outage this morning and disconnected for roughly 5 minutes beginning at the load screen. I promptly returned, finished the game and immediately received my notice that I was in a lower priority queue. Now I have to wait 20 minutes in a queue to play another......for the next five? Surely there is a distinction between someone who rages and leaves the game for good and someone who experiences a technical difficulty and returns to finish the game. Riot can't make a distinction between a habitual abuser and one who experiences occasional brief glitches? To say that I am frustrated would be a gross understatement. There has to be a more reasonable solution.
