I think- and this is just what I think, absolutely nothing official- the main reason behind the training changes is a response to the community being so upset about the salaries of big men. The community has said time and again that the system is not working. Players with ridiculous salaries have been a big sticking point on the forums. Recalculating salaries each season (another drop in wages this season- unmentioned I notice) is one way this has been tackled. These changes might, down the road, lead to slightly lower salaries for the behemoths.
Actually I changed my mind about cross-training. I don't like it that much anymore. I will tell you why.I have a 20y old Superstar and I want him to play in NT. His potential is a bit low for NT, so I have to make a specialized player. In order to make that work, I have to choose which skill I don't want to train anymore, and I chose Passing (he's at Prolific already). But in next two seasons of training it is possible that he pops in Passing anyway. This means that because of that pop in Passing, I have to give up at least 3 pops in DR and 2-3 in HA because Passing has a great effect potential wise. I don't want that! In this retrospective, my future trainees will all have to be Hall of Famers...not very good.The best alternative I can think of is that we choose where should that 10% go to on weekly basis. Now THAT would be great. It doesn't matter if we can choose between limited number of options for secondary training; can you imagine you set OD training and as a secondary training you can choose DR+HA+SB or DR+HA+RB or SB+RB+HA?
The idea is that the team will always be better with self-trained players than buying older ones
