I agree with 2 short rests. Also agree with requiring long rest camping to be outdoors, but maybe with an exception. It would be nice to have the option of making a makeshift camp in a cave for a long rest with risk. For example, potential random monster attacks that are not with exp to prevent farming, but a risk vs reward situation. I know in tabletop games I’ve played, there have been situations where we’ve made makeshift camps in hiding in very risky territory. It’s just a matter of how much player agency are they really allowing us to have and how difficult or easy can it be to cheese since you don’t have a DM enforcing a bad payoff.
