All the points you mention have been done to death, all suggestions falling on deaf (Nordeus) ears.
It infuriates me when I release a youth player to be greeted with the message ' xxxxx xxxxx did not impress' he never had a chance as you cannot even put him in training to access his potential during the 7 day window you have to offer him a contract.
God knows why his wages are also blank, other than the fact that depending at what star level Nordeus sell him at dictates his wage structure for that server.
It's a total nonsense!.
