yes, agreeBut we got to start somewhere if we are to figure this game out!!
so I believe that the target must be
How can we improve/develop our players with the new training, spending less sources.
That's why I started the tests and the guide about fast trainers.
If and how are they more effective than other players it's still questionable.
But the profit is that you can develop (the quality of) your team with less sources.
