One thing I've noticed in the EA, is that Advantage to hit or a check is being handed out at no resource cost. Presumably, this is to due to missing or failing not being fun. For example, one can simply walk behind a foe and receive advantage to attack in Larian's system. This design really belittles all the spells and class features that offer the player or their team-mates Advantage, or imposes Disadvantage on enemy rolls, that require resources to use. That makes these class features and spells, many allowing the foe a saving throw to shrug off the effect, more than redundant.
Since the Advantage/Disadvantage system is at the heart of 5e D&D, one would need to redesign all of these class features and spells. Is this even a tenable solution within the system? Now, I'm not of the mind that no changes need to be made in a system when it's transferred to a different medium, but I fear this breaks the system. 'Breaks the system" is not hyperbole, if one looks at how these abilities and spell effects work within the context of the system. These abilities and spells have a resource cost, are unique aspects of certain class/sub-classes, or require the expenditure of spells slots and the enemy to fail a save. What if the spells and abilities granted to you on level up are willy-nilly given to other characters at no resource or opportunity cost? This is what is happening, unfortunately.
