Opinions on Current LeaverBuster System

So as some of you might already know, this thread is about my current opinions on the LBS (LeaverBuster System) and what I think can be done to improve it a little bit.

I think the LBS is currently a very solid system, as now it requires AFK'ers to play 5 games but wait 5, 10, 15, or 20 minutes before queueing. The positive is that now people can't just go on their smurf accounts and play on it to wait the ban out, as several people have multiple accounts at their disposal. However, There is one thing I wish could change.

I think that there should be some sort of refresh system because even if you got a 20 min LB and you get LB'ed again but haven't DC'ed in a long time, then you still serve a 20 min timer before queueing. My idea is that per 50 games played without constant AFK's or something, then the LB time the next time someone DC's should be reduced, to maybe about 15 minutes. Then another additional 50 games for another 5 min deduction.

This way, people like me don't have to constantly wait out 20 minutes just because they DC'ed two games from bad Internet connection or game crash.

This is just my opinion, and so I'm not asserting that changes have to be made, but this is just my reflection on on what can be done to make things a little easier for players.

BTW LB does not equal
