Group training is literally waste of resources, because different positions have own low and high attributes, so I'm forced to train at least 18 players individually, 3 times a day, times 2 teams (used to be 3)... That's 2-3 hours per day...

And, after 8 years of playing, I really hate to do it...

Training should be passive, like in Football Manager, with active training only for team bonuses and if we want to raise quality of a player within short time, using rests...
