One of my main issues is forgetting to have people roll for it after a session. It can then build up a bit too high making for a tougher roll than they would have had.
So far it seems like it's advantageous to get just a littl Conflict once a game, so as to improve your Morality, potentially by a bunch. In a way it makes some sense, as you have a chance to learn from your mistakes.
But has this been an issue in your games? Have you had people degrading their Morality by their actions? Or has it increased too high and too fast?
