Okay. I'm not saying this is the way your mind works, but it's the way a lot of minds work: Emotions reinforce memories and expectations. People remember the time they got to use the ability a bunch of times not just more positively but more vividly than the time they used the ability just once. Even if they understand the math, their emotional expectations become unrealistic, and it starts to feel like their character is underperforming, like the dice are willfully denying them out of spite.I disagree. If you go in knowing that you're only guaranteed to have access to it once, and everything else is bonus--though more likely with some powers than with others--I don't think there's any loss of agency there at all.
Now, the recharge system works just fine on the DM's side, because it adds variation to the fight and because the DM's not emotionally invested in the monsters' success. But for the PCs -- why put that in the game? What's the upshot?
