I really like this Destiny Point mechanic. I use this kind of rule in my own D&D game (I even happen to call them Destiny Points as well), though I never had a concept like Burning vs. Spending points. I just had the equivalent of Burning. In D&D terms they were about as powerful as a Wish in many ways, but much more limited (can't spend a Destiny Point to make a mountain of gold appear, but you can save your own life from certain death, rally a group of people to fight at your side in a battle, etc.).
This version feels a lot like how my own works story-wise, but the added minor uses of spending them is a very cool twist.
