well.. I think that. If you need 50 points to do a DC as a MC... a "normal" player of top eleven needs more than one season to do this training and learn a new position...
and everybody here knows that usually we can use the our lovely players of the team during 1-2-3 seasons.... (-.-)'''
if the player is in a "not correct" position, if I am right he loses a % of his speed...resistance and all habilities.. no??

so my suggestion is to change the 50 points and be 15.
Cos is not real use all one season to train a player for a new position and it's some boring to wait for 50 points... I think a "normal" player, can have 15 points in 15 matches, that's a 1/2 of the season and I think that's the right way for this game, cos at now nobody uses this option. (as the negotiations, not a lot of people uses it cos it's so bad... well I use it only with friends...-.-''' cos u cannot select the players you wanna sell and I (all people) recives low offers for players that don't wanna sell... but (-_-)'''''''''

No more to say. (^-^)
Enjoy!
