Mistake#1
Thinking that training is possilbe at your level in the game. This is not really your fault. One would hope this game is set to reward you for training your own players...that really only happens in small nations where they have the finances or established teams taht bought pre created players at around 22. Its just the way they set this game up.
This game has rewarded me for training my own players. I think your comment is ridiculous. It seems to me the most efficient and cost-effective way to improve your team in lower divisions is through training. We all realize you're frustrated with your personal training results; no reason to take that frustration out on the newbies.
Absofreakinglutely.
I always see people telling new players to get 2-3 players with high, high potential and one position train them, and saying that anything below allstar is worthless. Meanwhile, I've just happily chugged along two-position training with star potential guards for the almost two seasons now that I've been here, and just now am ready to switch to one position because I want to start transitioning to big men via a SF trainee.
It's definitely a different game in different countries, but in a country with five levels, you're darned right you can train to improve your team quite successfully and to make sure that you end up with players built to your specifications, rather than hoping that you can find someone that's not a JS donkey on the TL.
