Instead of " decreasing " the income from drills and limiting the options of every manager to train his player the way he wants, you should have done the following

1- Create a different page for each position that doesn't include dark skills.

2- Create a new system of drills that target the skills of each position ( no more drills for dark skills )

3- Improve the draw system by making it smart not dumb like now

4- Create a double version for the game and allow the manager to chose either option he wants to play : Amateur - Professional and differentiate the level of competition among them ...


By applying such steps you would have solved the problem and minimized the amount of criticism
