I see that my skill blooms idea was rejected so I thought about Career lines. It's the same training just faster or slower. lets say that 100% is current speed. but player would have some periods, when his skills would grow faster or slower from (50% to 200%). If old player has green 170-200 % period, it means that he will grow 1.7 - 2 times faster than current speed, so probably it would be faster than young player in current speed right?
Hmm... would be interesting to have here players which can grow slower but for almost whole career. I dont think that is should be like that they have to have same training rate on the age 22-25 like normal players on 18-21.
In fact they could have it like 24 old players but from 18 to 28, every year is the same. And it would not be complicated for anyone to understand. Of course, you can waste your space by training them on 1 post, but more efficient would be to train more of them 2 post.. And after 28 they will be soon dead anyway.
The reason why Im suggesting something different than this:
http://img684.imageshack.us/img684/4117/extraordinarycare.....is the fact that it could be efficient only for NT teams (farming) - current slower training and potential cap is a rescue for trainers of NT players, which are not forced by NT managers to sale players in late age if they dont want to train them and doesnt want to look in eyes of comunity like selfish centre of Universe.... so is a good thing that the training cap is here relatively early
Other way - normally you have to develop player for sale or for your team, but you never can afford to waste with anyone his whole career, unless there would be like 5 of them (I suggest) (or lately the whole team - team training).
Anyway it should not be hidden atribute, because it would be insane to find someone like that on Transfer market.
