Is Powertraining a waste of time?

[nikolgiorgos]

There are two cases.
One is the beloved of asso top 100 teams.
To make a mutant squad , staying in the same lv without using those players for official games so to keep those stats and use them only for asso games.

The other case is also go for titles, treble etc (so to promote every season).
In this case what most of the teams are doing is playing a lot of friendlies, not power training.
p.t. is useless for old players with high white skills.
