I think it's interesting that a manager is stating that these are issues that led mangers to leave the game. Really that's all the matters. Only the BB's have the means to survey active and inactive users to gather these details. I'm skeptical that either of these end up keeping more managers in the game then they chase off. Will likely never know either way.
When it comes to deciding the quality of a feature I almost always side with the reality test with rare exception (injuries are one of the rare exceptions). Neither of these items are realistic AND their ability to improve the overall game experience is debatable. All I know is that if I was to recruit a new manager or mentor a new team these are among the most confusing items to explain and live with. *cough cough, Mahody* :)
Yeah I can understand your point of view, but I don't really share your skepticism, because these things add depth and strategy to the game. Without an enthusiasm system (or something similar) and a training system that requires trade-offs, BB becomes more like checkers, and less like chess, and I don't think that helps the game long term. I wasn't around back then, but I can assume that the game has probably grown tremendously between season 5 (when the OP decided to leave BB) and today, and it did so 'despite' maintenance of the two systems we're talking about?
The fact that a manager has singled out these systems as reasons he left the game is not particularly interesting to me on it's own either, because: the only people who are going to be posting reasons they are leaving are people who don't much like the current game; nobody is going to be posting that they left the game because they love the training system so much. In fact, since your post about changing the training system, three managers in a row have said that the current training system is actually something they distinctly enjoy about BB.
So, people who aren't happy with something are only one side of the story, and people who stay don't often spontaneously post lists of reasons why they're staying :)
(That's not to say it isn't important to get feedback about what people like/dislike.)
As far as reality goes, I'm for more realism too if it
adds to the game, but in the end this is just a game (there's nothing realistic about a 20-something college student owning and managing a professional basketball team in his spare time via his laptop) and the most important thing for me is that the game remains fun, complex, and addicting, and I think there are plenty of features which are not true to real life but still add significantly to those game dynamics (ex: promotion/demotion, training system, TL, etc.)
