I fully understand it is a ROLE PLAYING GAME. In fact, that's why I suggested what I did. As a DM, I would never let my Players long rest willy nilly all over the place after every battle. Long rests need to male sense. The DM should be like, "Um. You sure you want to long rest? You have a tadpole in your brain. Plus, there's a ritual gonna be completed any day now."
So, my suggestion is to help keep spamming long rest from happening. Since there is no live DM to stop players, there needs to be some limitation to prevent it. Otherwise, it negates other important features of the game.
