Been playing over 10 years as well and agree with a lot of what you say.
One thing that's always really annoyed me and has never changed is that when you buy a player on auction it would be so good if he carried forward any training of SA or position to his new owner. On the auction list you don't have to show the progress, just what is being trained
Don't know how many players I've sold who were close to a new ability or position in training and that was all lost due to transfer.
What a great bonus for the buyer as well finding a player who hardly needed trained .
