In 5e, short of permanent death PCs are completely healed in just 8 hours no matter how much punishment they received and totally without magical interventioni. It almost seems laughable, especially to those of us who played AD&D back in the day. Even with the proposed rule, no injury takes longer than 5 days to heal. Actually a pretty liberal standard when you think about it.
Yeah, that was my sense of the healing rules too. My players like them though, and I'm of the philosophy that the rules/house rules should usually be collaborative, not created top-down by the GM.
One minimal "change" would be to use the standard 5e rules, but only when there's a magical healer available, such as a cleric, bard, or druid PC. That sort of models how most healing happened back in AD&D, at least AFAIR, with the cleric spending time healing everyone, and then taking a long rest so the cleric could prepare spells.... Functionally, it's pretty close to what 5e does.
