See, that I think is the heart of a lot of the problem. HP have always been this. But, at the table, many groups have narrated hit point loss as physical wounding. Since the vast majority of healing in D&D for decades has been magical, this isn't really a problem. "Gutted like a fish" at 0 HP is perfectly fine when it's going to take magic words to bring you back.
The problem started when we tried to add in non-magical healing that was actually effective and useful at the table.
Yes. This post nailed it. I tried to XP you but couldn't.
For this reason, I like the option of adding more gritty systems like wounds or injuries. Using teh Disease Track works well for this, as did the supplement on using an Injury Deck from Dragon a couple months back. Though I think it needs to remain optional, because not every group wants that level of grit and simulation; they're just fine with fluffy abstract hit points. Heck, this is something that can (and probably should) vary campaign-to-campaign!
