Part of the real beauty of the system, as I see it, is the constraint factor. You can't hole up indefinitely in any little cave, because sooner or later you need to come out for consumables.

You can't keep running around on attack forever, because sooner or later you need to gather something (unless you are just that good), which gives an opportunity to for someone else to find you at a moment of weakness. You see that log of Fjodir getting the jump on Eleagra while Eleagra was going through a bunch of stacked food commands?

A few classes or items that prevent this issue are an actual advantage. Rangers don't have to come out of hiding in order to eat and drink indefinitely, so they can sit around in camo forever. People that dodge have an implicit cost associated with keeping themselves lightweight. Etc, etc.

It may seem like a minor thing, but it's like the ante in poker.
