I'm having an issue where it seems like the players aren't using hero points as often as they should. It seems like one of the basic mechanics for hero point gain is selling unused dice. The issue is that this results in danger points as well, which I think I might have scared them off of.
Essentially in the first session I introduced one of the most basic uses of the danger point (increasing the necessary amount for a raise) during a risk I wanted to feel dangerous. The players were still able to get through the risk without any huge consequences (they took a few more wounds than they otherwise would of, but all of the narrative consequences were avoided). Nevertheless I think it really shaked them that the GM has the ability to casually up the difficulty like that.
Since then they've been treating selling unused dice like a deal with the devil, despite the fact that I often forget to use all of my danger points each session, which I worry is causing an overall hero point shortage.
What experiences have you guys had with the hero/danger point economy, should I be worried that my player's are gimping their own access to hero points, or are they right to fear the danger point?
