There are too many economical changes too often and it's more and more difficult to plan a long term strategy.
One thing to keep in mind is that NOT making changes is a change in and of itself, there are lots of variables which are progressing over time... teams are getting larger salary bases, teams are getting larger arenas, more teams in buzzerbeater. A set of rules today and that same set of rules tomorrow will not be the same game. Our changes are meant to try to keep the dynamic buzzerbeater economy headed towards longer term stability.
Without these changes we believe the gap between the upper divisions and lower divisions would increase, and we are clamping the gap to be about where it is now, and making it easier for teams to transition between the gaps.
We understand that it makes it difficult to plan for long term strategy, and this is why we always announce changes like this way ahead of time, to give people time to prepare.
...that means that upper division teams will become richer than before compared to lower division teams, doesn't it?
No, if the mean of x (<x>) stays the same, but the variance of x <x^2> goes down, then the difference between <x>-<y> stays the same. in this case y meaning lower division team income, and x being upper division team income.
