Hit dice worked the same way since pretty early in the D&D Next open playtest, with the only significant changes being when they increased the length of a short rest to an hour, when they removed the requirement to spend a use of a healer’s kit to spend them, and when they changed long rests to only give back half of your HD instead of all of them. They had plenty of opportunity to iterate on the mechanic during the playtest but didn’t, which suggests to me that it wasn’t a matter of not having time to develop the idea, but rather a matter of the mechanic having been satisfying enough for enough of the players polled right off the bat that they were afraid to mess with it too much from there.6. Why is the HD rolled to regain HP mechanic in 5E is half-baked?
And the answer is because WotC realized they needed to not make people reliant on magical healing, but hadn't come up with any particularly good solution by the time they "went live" with 5E, so went with a really underdeveloped approach. Worlds Without Number does the obvious thing and makes magical healing "use up" these HD, and I hope DND2024 takes a similar approach personally.
I’m hoping that the autognome in Unearthed Arcana is a sign they finally feel like they can explore the design space of hit dice a bit more. Fingers crossed that the ‘24 revisions do something with it.
