Please change the spell rest to reset system to a Cooldown system, for Baldur's Gate 3.
Larian has made a few too many tweaks to 5e rules, sometimes for no obvious good reason; please don't request more. There are several ways to address your concerns without changing a fundamental 5e mechanic. The general issue is that players have figured out that camping costs nothing but player time and not much of that. There are warnings about time passing, but there is no noticeable real penalty. If there were, the mechanic could stay as-is, or something quite close.

Why are you using all of your spells and other resources every battle? Most battles are quite survivable and even winnable (no PC or desirable NPC death) without spending spells and abilities like crazy. Short rest recovers some resources for some classes and will take care of most battle damage. Consumables, which are quite common in the game, will take care of a lot of the rest, and scrolls can be used instead of spells. As has been pointed out for many other topics, just because you have the option to abuse a mechanic doesn't mean you should - challenge yourself to win battles with mechanisms other than 'spam highest attack'. Also, just because you have the option to abuse a mechanic doesn't mean you should ask Larian to close out the option for everyone else.
There's a general problem where game companies want to appeal to broad audiences and, since people don't like getting creamed unless they are dedicated min/maxers who understand the mechanics, games that want wide audiences have to be designed at less than 'mix/maxer only' difficulty levels. But that leaves min/maxers complaining about exploitable mechanics and things being too easy.
