I've always thought of HP as pain tolerance. If you think about it in terms of something like WoW it makes more sense.
You build your Stamina which gives you more hit points. Now, in a game like WoW, you're constantly being beat on by various weapons and spells. However, with either the right magic or the wonderful healing powers of food and bandages, you can withstand huge amounts of torture.
I always figured it as magic heals your wounds to keep you from dying but there comes a point where the pain becomes to great and you eventually collapse without any magic to maintain your body. This also accounts for such things as poison and bleed effects.
I've spent the last few minutes trying to explain exactly why I think WoW is the worst offender here, but then I realized that I think Bliz is actually on about the same page as me.
So you start out at level 1, and you gradually grow in power and ability until you reach level 80. Along the way, you fight evil across two worlds and make the world a little bit safer for your fellow sentient beings. However, as capable and skilled as you might be, you will
always be massively dwarfed by the power and strength of any given dungeon boss, and swatted like a gnat if you try to take on any of the faction leaders solo.
Basically, WoW scales with you. You're really not much stronger at 80 than you were at 60, or 40, or 20, at least according to the setting's internal logic. You've got a broader suite of abilities and much more impressive gear, but if you went back and fought, say, a version of Mr. Smite who's scaled to your level, you'd still get stomped into the ground. (Well, pier.)
So what I'm trying to communicate through this long and rambling post is that I think WoW already views your hit points less as "pain threshold" or "how many hits you can take before you die," and more like a formula derived from your skill, equipment, and experience relative to the world around you.
I have no freaking clue if any of that made sense.
