demands players use foresight and planning to gauge their resource management
Just roll a sorcerer, pick the spells that are always useful, and you will never have to worry about planning anything ever again.
That isn’t what resource management means.
Resource management is something that only wizards have to worry about, and not even they really have to worry about it that much after 5E, especially given the abundance of party supplies.
We are talking about Dungeons and Dragons in general, not BG3. And all characters have resource management. Hit points are a resource. Potions are a resource. Spell slots, ki points, action surge, wild shape are all limited use resources.
