I spoke to Nordeus via Twitter about Personal Trainer being rubbish feature... If you want to train your just 2-star player into 3-star player you'll have to spend 320 tokens, and for all those tokens you can buy 6 scouts... You know what they answered? Then you buy 6 scouts!!!
Sounds about right. It is just a money making exercise for them with little regard for the end user.
They probably know it's a rubbish feature but someone somewhere will be using it I'm sure.
