The problem with high HP regeneration or Mana for spellcasters was that you still needed to sleep to forage and repair equipment. Otherwise just a short walk would bring you back to full strength.
You don't need to repair all that often to keep your equipment in good shape, even with a relatively modest score. And I'm usually too impatient to camp for forage. When I decide to forage, I dedicate myself to it and spend a few weeks down by the docks in Port Kuudad. It's less dirty than it sounds, I promise.
