To me the "pro" league is OK, I am not crazy about the idea but I can live with.
The "more than 0' league is nonsense, you want to erase HW sharing but you create an other suspicion subject
The best score only gives score for the team : I don't like it that much as well, I don't see how it will prevent for Sharing as I am not sure that most of the members care about the team but more about their own personal amount of points
