It's true, we can't cover all the suggestions and discussions on the forums, it's just impractical time-wise. But, we do read them when we have some free time.
That said, more on topic, the system has some of the mentioned training prerequisites intentionally implemented to make training harder. Real life and and online sim can't align very well in this respect, and it should be hard to make choices between training speed and match effectiveness. Tradeoffs are key here, so we might not want to remove them or we'd make the game too easy (boring and not challenging). We can make tweaks here and there, as we did a couple of seasons ago, but tectonic changes will not be implemented as they would enrage old school managers. Easy does it, is what I'm saying.
