Is LeaveBuster Too Much?

So A few days ago i got a leave buster for afking, now this thread isn't about me complaining about my leavebuster or anything but it's the fact that I can't get rid of it. Sure enough I deserved it but i have attempted about 11 times now to complete it and majority of the time I'm playing overwatch in the background waiting for queue to pop. But when i get to around the 5 minute mark my league either A. Crashes somehow or B. league of legends "removes me from the group" therefore making it so i have to restart my queue all over again and wait the full twenty minutes. Now i want this thread to be opinion based do you think the leavebuster system is too much? should we have a different punishment system? or should riot just fix the leavebuster so you can do stuff while waiting? I understand that there has to be a punishment for these kinds of offenses but when i'm waiting up to 2 hours to play one game, it gets to the point where you have to ask yourself when is it too much?
