Left to me. I wouldn't care much if team with the highest SF at the end of the season emerged as LMS winner.
That would be boring. The main purpose of LMS is the rebuy - to increase the reward and decrease the competition over time.
It works as an added risk/reward element - for those willing to rebuy knowing they can still lose it all in the last round although they have a big advantage.
SF is not a good metric to take at all - some games you win 3-0 without your opponent showing up. Imagine how it would look like if LMS was won by a Div4 player because his opponents didn't show in 4 rounds?
Even better - imagine if a player loses SF in a crucial round because his opponent didn't show up. Imagine you have 8 correct answers but you win only 3-0 because it is a walkover.

I honestly feel LMS is in a perfect state, this season has been really good and is still quite exciting with a lot of rebuys, even from lower divisions.
If you ask me, there will be no changes to the current format in the next season, and I think Trofo will tell you the same.
