1: Do you really think the way the training method is today is good? The most perfect possible?
Its not the worst ive seen, but should be better.
2: You can be competitive in the major leagues, and trainning for your NT squad? A SF for example?
I have never been past D.3 and fought for relegation the entire time i was there while trying to train.
3: If you start now, and knew you could not train and be competitive? You motivate with the game?
i enjoy the game and have recently decided to go homegrown, so i would probably still play.
4: If you think you should change something in the training method, what would you change? Not necessarily something drastic.
I wouldnt change much honestly, i would just eliminate the positional penalties and simply make it 1 position 2 position or team training and i would speed up training so 2 position is more like 1 position speed and 1 position is about 1 1/3 of the current speed.
With height playing into formula you could even say they boost it a little to make it still challenging to train bigs in guard skills and guards in big skills.
5: You would be somehow nervous, angry, unmotivated, if something about the training method, was changed?
If it made it worse, yes. As long as it betters the training i would be all for it. However some of trainermans (sorry to call you out) ideas i have read are simply overboard. Training just needs some small tweaks and it would be perfect i think.
Fix the out of position issue which plagues the game and more people would stay.
