I'm okay with HP being more than just physical wounds, but this definition of their abstract-ness frustrates me to no end.
Let's say Bob has 30 hit points and an 18 AC. George the Goblin rolls a 19 to hit, so that hits Bob; George then deals 8 points of damage.
Assuming that when you hit bloodied is when you first take actual damage (seems a legit assumption), that means that Bob was not actually hit by the weapon - he dodges, or it's a near miss, or George screwed up his swing a bit, something.
...but isn't that represented by the attack roll?
It's a question of correspondence. What does the attack roll represent? What does the damage represent? Some people are okay with these things being nebulous, and that's cool, but these things irk me. I want these things - HP, attack rolls, damage, AC - to be relatively "concrete" things. Abstract is fine, but the abstract definitions shouldn't overlap, which seems to be happening here.
And just in case... hong, I have no interest in hearing your mantra again.
The attack roll represents an attackers variable chance at harming (with the most looseness of the term) his opponent.
AC represents a defenders static ability to defend himself.
HP represents how well any given character is doing in combat with regards to staying in the fight. Too much bad luck, low morale, physical wounds, or any combination there of puts you out of the fight.
At least thats how I view things.
EDIT:
In combat terms, the act of me trying to attack you is not constant. There are many variables in how well I am going to be at attacking you in any given situation. Your ability to defend yourself, while also highly varied, averages to a simple static ability. If my ability to attack you is greater then your ability to defend yourself, I "hit." Now what does that actually mean in game? Nothing what so ever.
HP cannot be modeled what so ever in game. It is an out of game concept used to evaluate how well you are doing in a fight. Now as this is a game after all we may say that I smash my axe into your chest, but in game that never happened. If I really smashed an axe into your chest, you would be dead. Plain and simple. It doesnt matter if you are epic or heroic, if a axe smashes into your chest, a dagger is stabbed into your kidney, your head gets chopped off, you die.
Now abstractly you can represent it as luck, morale, etc. try to explain it as I did above, but in the end it doesnt exist. You dont fall unconscious from a lack of morale. You dont die from a guy shouting at you. We use these terms to equate to ourselves, just as we do with physical attacks, how well we are doing in a fight.
