just spits on abilities such as Goodberry, Cure Light Wounds, Lay on Hands, Healing Word, Potions of Healing, Action Surge, and more.
What about in a scenario where all those abilities have been used and you are in the middle of a long combat? Wouldn't the ability to consume food help with that?
It would make this combat easier, yes. But realistically you should not have gotten into such a scenario, especially with the ability to freely long rest in BG3. A very important aspect of D&D (that all the classes are designed and balanced for) is resource management. You chose to cast your spells in earlier fights AND not long rest AND not have healing spell scrolls/potions as a backup. Maybe you had to use your spells/consumables because there was a difficult combat. Or maybe you just were being careless, using healing spells instead of the short rest mechanic. Either way, the better solution is to rest and/or buy healing potions, not add in a safety mechanic that invalidates core components of D&D/class abilities.
I could just as easily ask: What about in a scenario where all those abilities have been used, you're in the middle of a long combat, and you have no food left. Wouldn't the ability to restore hp with the click of a button help with that?
The answer is the same: yes, obviously it would make the combat easier. But why bother having healing spells at all if you can easily heal with commonly-found and inexpensive resources?
