Dudes you need to ask one simple question, Is the 40 skill points you need to get on worth the wait for it? I found by the time I trained a SA its nearly half to two thirds of the season gone and so as soon as next season comes the player loses a star and in all honesty the star becomes void because a good higher star no SA player is as good if not better than the one have trained! so in my opinion its a 100% NO.
