We are probably not in agreement, or halfway there.
I meant that those exact classes may get overpowered if short rests may become to frequent. And the fact that we don't know yet what Larian will do about it.
The problem is that currently short rest classes are underpowered. Based on games I've played/others' comments, D&D classes seem fairly balanced for ~2-3 short rests per day. So BG3 should have around that many short rests per long rest.
I think that simply allowing 2-3 short rests per long rest would go a long way to limiting long rest spamming. People would feel less obligated to long rest after every encounter, and thus do it less frequently.
And about the actual D&D system... loss of hp isn't actually a wound. HP stands not for literal health but your character's grasp for life in general:
Hit Points represent a combination of physical and mental durability, the will to live, and luck.
Keeping that in mind sleeping or even eating to full hit points seems quite logical. We are not wounded, we are simply exhausted by fight.
Yeah, yeah...I know. I still don't like it.
Even if
some HP reflects mental durability, will to live, and luck, that leaves some HP as physical injury. If my character reaches 0 and is unconscious and dying, I would hope it's because of blood loss and not because they've lost their will to live. But, sleep for 8 hours and they're totally fine!
