f the changes are best for the game, the changes need to be made. The best managers will adapt as always and find ways to thrive in the new environment, and those who have followed in their footsteps to achieve success will struggle until they find the new footsteps.
Imagine a manager who has two PG with 20 OD and 15 IS. Now comes the salary update and because the cost of OD and IS has increased just a little bit for PG/SG/SF, their salary increase of 50k (that doesn't seem irrealistic) => 100k for both. The manager cannot keep them and has now to sell them... As all the other managers in the same situation => low prices and a big financial loss. Sorry but that's unfair.
I would prefer an increasing of the outside shot %, or a decreasing of the cost of JR and JS for SF.
And while I agree that you ideally don't negatively impact anyone, any change you make is going to hurt somebody - make outside shooting higher percentage and you hurt those teams that have the high OD/high PA/ low JR players since their competition will benefit and they won't. If you reduce the cost of outside shooting further, teams with expensive outside shooters will suddenly have more money to augment their team while the LI clones wouldn't. There's simply no such thing as a change that will not affect anyone, period, end of story.
The simple truth is that what's best for the game is what's best for the game, and I certainly hope that the decision makers use that as their primary goal and then seek to minimize the disruption for anyone effected by the changes, rather than having a primary focus be on ensuring that those who have thrived continue to thrive.
