Ok. True. Then I will add that they must rebalance certain dangerous areas so they CAN be beaten without a long rest regardless of whether you are level 2, 3 or 4. There needs to be some sort of auto-difficulty tweaking that occurs or something so you aren't totally stuck replaying whole sections over and over again.
Example: HAG'S LAIR. That entire area is HARD to beat in one fell swoop without gimmicks. First playthrough was a nightmare. When you don't know what to expect...
Disagree. There should be certain areas that are incredibly difficult if not impossible to beat at certain levels (e.g., Hag Lair at level 2). As OP said, in these areas you'd be able to walk back out to a safe area and long rest, so you'd be able to come back at higher levels. No reed to replay it over and over unless you actually want to for the challenge. I don't want enemies to auto-scale to my level.
