Devs are afraid a proper Long Rest and resource management system would alienate casual players. That's why we get a half-assed D&D system with unlimited resting, neutered control spells and stat bloated enemies to compensate.
Maybe they did try to create a proper Long Rest / resource management system but couldn't figure out how to make it easier for casuals. In EA there were remains of a fatigue system, too.
Would be great if they could restore all that and offer a D&D Core Rules mode in a definitive edition. Like balanced difficulty but with resource management.. random encounters etc.
