We play over Fantasy Grounds (have for a decade--I'm an FG hipster) and the combat tracker shows monster hit points as Healthy, Light, Moderate, Heavy, Critical, Dead/Dying, with 25% break points. I started using those descriptions in face-to-face play because it's about how much information I want to give.
And I roll all damage, because I'm playing D&D, and I want to roll damage dice too.
