The thing I like about danger zones is that they make you think differently. “Oh no, I’ve run out of spell slots. Maybe I should sneak around to avoid combat or maybe I should start using these consumables I’ve been hoarding the whole game.”
If you’re able to backtrack out of them though, it kind of defeats the purpose. I’d rather they be zones where you are trapped but have lots of potions and consumables to find if you search. Maybe even introduce a consumable that replenishes a spell slot. But I totally get why that might not be the way most people want to play. Honestly being able to spam long rest isn’t the worst thing in the world. Most video games let you heal and replenish your resources instantly anyway. It gives you the flexibility to not hold back with your spells so much.
