They should remove the damn thing completely!
Make it dependent only to minutes management.
I don't fully agree here. Game Shape training does need to be in the game because this is a fantasy simulation. I know I have forgotten to set a scrimmage game training rotation in the past. In one particular case, it was the week before the playoffs!
If I did not have the option of GS training, I would of not promoted that season.
So while it may not be the greatest thing in the world, it does need to exist for time when team owners forget to log in.
I would be happy with GS training 3-4 times per year. That would protect me from my own stupidity... while not letting it get to abusive.
