I totally agree, I loved the Endurance/Health system since I first heard of it.
Taking a hit (every single one) meant losing permanently hp (until resting) but on the other end wasn't too bad since it didn't penalized your characters with malus or something like that, this system fixed a number of things:
-Being hit becoming meaningless because at the end of the encounter you'll be healed (or worse you have the chore to manually use magic/potions to heal)
-Since every single hit has an impact it isn't a "binary" system that as long as you aren't knockdown you are fine and you won't get any kind of penalty (and likely be healed at the end of combat)
-Infinite healing during combat
With the plus of limited resting supplies to put a stop at spamming and give a real impact to the system, this or any other type.
I really hope they'll think about keeping this system in place
(sorry for the bad english)
