Well, what you say it could be another thread. But talking about it, I would say I am not agree with you. At real life, a young football player (with talent) training a practice match, can progress a simply skill point, aleatory added to his actual habilities. And a talent young player (18-21) could so progress aproximately a whole star (75 skill points) in a season. Of course this is only my opinion but if it wasn't right I am pretty sure it would be close to be right. Just aproximately. So I don't think nordeus is not doing UNrealistic at this point.
But this is only my opinion, I am agree that maybe at this point could be a lot of difference opinions. And this would be another thread.
