Best way to prevent injury

Friendly games, you choose your opponent, that the game are likely winning you get 2-3 moral packs, 1 rest pack and 50% you get a treatment pack
dropping morals are no longer a factor when u got 2-3 per game
i do wanna know where to spend my moral pack when my team always got 50+ around and the players are all moral fulled
