4. They provide a setting that allows players to toggle camping resources on or off. In my opinion, this is Larian's best option. If they allow players who hate it to choose the BG1/2 system, and players who love it to keep camping resource management, it is essentially a win win. I don't think that anyone, at any difficulty, should be allowed to use food to heal. It sets too dangerous a precedent and has no place in a D&D game.
I agree 100%.
I personally really enjoy the new system. Yes, it needs to be improved but it's not a bad concept.
As others have already mentioned, make it more like crafting: for example, maybe we could combine a specific amount/types of food into 1 pack supply unit with an unique name and icon (for example 'red meat camp supply' or something on that line) and each type could provide specific bonuses when consumed. Maybe red meat gives combat bonuses to strenght-based characters while fish gives bonuses to dexterity and so on.
In general, this system makes the game feel more real and immersive. I actually had a lot of fun searching barrells and boxes looking for food supplies until I felt I had enough.
