I'd say "no" for my opinion, because it's the FAST recharge times (1 round, 1 mintue, 1 hour, etc.) that give me the "martial arts movie" feeling that I don't like for my D&D fantasy. Heroes who have to rest up for a long time (half a day, a day, a week, etc.) after blowing all their hit points and powers are more what I look for than just, "OK, it's the next scene, you've got all your powers back and you're healed up." Good for martial arts cinema, good for Feng Shui, Good for Superheroes, bad for my D&D fantasy.
