I personally don't see it as necessary. I don't care if it's ever wildly popular, but I do want it to be fun with a touch of challenge that you're aware of and accept from the get-go, namely that the dice can ice you over at any time, and that includes hp and energy, but the common etiquette of a mulligan or the "inn keeper ruling" may still come into effect. (That being said, there's always equipment, and Baby and In-Training Digimon aren't meant to be fit to fight.) So, while I understand where you're coming from, I respectfully disagree as to that being the course of action I want to immediately take.

Game the system how? And if you're looking for cracks in the wall, I feel the more gentlemanly thing to do is make it know, not shove your hand in it. (That being said, I find the one-to-six "health" pseudo-system a bit to easy to game, and too much like the DM is willingly tipping their hand.)
