Unfortunately, they've already said they wouldn't implement cover due to the difficulty. Presently, this unholy union of DOS systems and 5e is quite a mess. They really need someone on their team that understands how 5e abilities interact with one another, these zany design choices make a host of abilities and spells meaningless, the waste of an action and precious resource for a benefit that can be gained just a bit of movement or entirely for free. The entire function of these spells and abilities, some of them keystone abilities of the classes, is to grant advantage at some resource cost, or to provide something unique that only their class can do.
