There is match income, training, and the minutes do count (which makes squad rotation more difficult). Yes, it's a challenge, but then again these are the best teams in BuzzerBeater! (And, if it's too much of a challenge, you'll be gone in one week, right?).
This is really a bad idea, in my opinion.
4 games a week means:
- extra income
- more trainees
the only drawback is that a larger roster is needed, but still it creates an unfair competition among teams.
And more important. I do appreciate your effort to continuously improve the game... but important changes should not be introduced with such short notice (same happened for game engine changes and training potential).
