And maybe one addition to my previous post, our goal would be to give small increase to revenues for some type of teams and decrease of costs to other type of teams. But not benefit only particular teams and give less benefits for any other team, as might happen if the Merchandise boost is the only new feature.
So as a example, if a Team A plays in Div3, they get +5k to revenue, but Team B only 2.5k in Div2. Then Team B with 200k salary player gets 5k decrease to salary costs and 5k more profits to merchandise and Team A with 100k salary player only 2.5k decrease to salary costs and 2.5k more profits to merchandise. But because Team A trains his current player, they get trainer for 50k less money and 5k less salary than previously. Team B doesn't train, so there's no improvements for him with trainers, but they can also buy a better doctor with 10k less money and 5k less salary than previously.
These were of course just examples, luckily I don't have to mess with the formulas.
