I wish they'd try implementing food similar to the way POE2 did (and Kingmaker to a lesser extent) - required for resting, limited in supply, and gives your characters a bonus until the next rest (based on recipes).
Not only will that fix the healing economy by making potions matter again, it's an interesting mechanic that can potentially help with the infinite resting problem we have right now - since if food is limited and it can grant you useful bonuses, you might not abuse resting as much.
In game, it could be something like a lesser version of the heroes' feast spell.
