Please refer to my post
(261684.18)In the 3 games that you mentioned above, you suited up 9 players in each game.
If training and the game in general was meant to be easy, noobs would have nothing to learn and people would quickly get bored with the game
Ensure that your trainees have high inept or above stamina, suit up only 7 players per game and use defensive swapping if playing a trainee out of position for training purposes
