closing game right before victory or defeat resulting in "low priority que"

shouldn't there get a counter or something that gives leeway to these types of problems. iv also been temp banned in the past for doing this. and its a very simple reason really, I just want to close the game as soon as its finished to get on to the next. as an example, I cant stand to see the "DEFEAT" logo that pops up in the middle of my screen, or even hear it. so why am I being punished for closing the game right before it officially ends?

come on riot... don't act like you don't know about this. I understand your trying to make your point made that "leaving games" is bad... lol ok we all know that. but think about the people who care, who are getting "punished" for such a perplex reason, as you can simply add a leave game timer. such as 60 seconds. before the nexus is destroyed.
