Again I feel the need to re-iterate the need to re-balance Camp Supplies. I genuinely feel the cost of Long-resting needs to be increased, most especially at levels 3 & 4.
I thought in announcement video Sven said that cost will increase with levels (and more resources to replenish). I haven't seen it happening ingame, perhaps it is not yet implemented?
If Larian considers tightening up resources at our disposal as the game goes on, making it easy to feed early on is a good design - allowe players to mess around a bit in act1 before they get the feel for the game and systems.
Well yes, all of my recommendations regarding the cost of camping *and* the value of food items is based on how the system *currently* works.....hopefully some re-balancing is in the works for patch 6. One thing to consider though is that, if high value camping supplies were much more rare and/or if certain supplies only had value when combined with other supply types (like alcohol requiring food, for example) then it might make spells like Goodberry & Create Food & Drink worth having.
Another thought I had was this-what if you could get a Cooking Proficiency for your character-one which allowed you to combine several low value supplies into a Meal that had a greater value than the sum of its parts?
Last of all, as I said above, a risk of a random encounter-however small-could also help to further balance out the use of the Long-rest system. It would also add greater value to characters with various Survival Proficiencies, as they may be able to use them to help camouflage the camp to make the chance of discovery even smaller.
