PA testimonials: Left 14 players before adding free reward Player Academy coaches to high AvQ players in order to slightly reduce team AvQ at the last day of the season(Day 28). I think this was not a smart strategy. System quickly allowed me send my player to training in progress even if there were not enough players remaining(13) in my squad. Apparently, the players who are at PA will be included in team's AvQ for next season draws.
The training will spill over into the next season. Bear in mind that your player's star will be re-adjusted depending on your league position this season.
