I know this thread is old and I don't like to necro things unnecessarily, but since it's now 2024 and patch 7 is coming up, I thought I'd address the current state of affairs.
There seems to be some misunderstanding/confusion/disagreement on the purpose and location of long resting. You already have a permanent camp set up nearby (who knows where). The game is fun because of the story, encounters, combat, etc. No one would have fun constantly trudging back and forth and back and forth from camp. So the "teleportation" is no different than fast traveling between waypoints. It's just a mechanic to avoid tedium and make the good stuff more fun. The same with "teleporting" items to camp. You could say, "ok we've got three heavy barrels of runepowder, let's truck these back to camp...trudge, trudge, trudge..." or again, to avoid tedium and get to the good stuff it lets you skip that part and just say "OK, we took those to camp and stored them."
There is one very important aspect of resource management in regards to long rest that I rarely see mentioned. Elixirs. Unless you "vendor scum" (save/rest/reload), many of the more critical ones, especially if you create a build around them (like Cloud Giant Strength or Viciousness, e.g.) are rare and you only find so many (including ingredients to make them which are even rarer). They only last until long rest. So if you're taking advantage of your elixirs, it behooves you make them last as long as possible (especially in Act 3).
The two things for me that are REALLY BROKEN are the fact that even though your other team members that aren't in the party at the moment are taking the ultimate long rest in camp, sometimes there for days or longer, they get no benefit from long rest. In order to avoid complexity about how long have they been in camp and such, it would be simple and sensical enough if a long rest restored everyone in camp, as it should.
The other thing are the Short Rests. A short rest is supposed to take at least an hour. Yet after a short rest, spells that last a couple turns are still in effect, fire is still burning on the ground, it basically takes no game time at all. Ridiculous.
I would like to hope these things could be addressed in Patch 7, but seems highly unlikely they will.
