Ok, so by that logic, you live in this world. How many bullets can you take before it kills you?
Probably between one and three, depending on how lucky I am. Of course, I'm not a mythic hero of legend, and my feats are not comparable to raising the dead or teleportation.
Nor am I typically wearing body armor, which
is a standard assumption of anyone who gets into combat. In D&D, if you can take a hit without dying instantly, then you're either wearing armor (fighter/ranger/rogue) or you are magic (wizard/sorcerer/warlock/monk) or both (cleric/paladin/druid). Sure, the rules say that you still need to get through HP even if you
aren't wearing armor, but that's an obscure corner case that shouldn't actually arise during gameplay, and I'm not going to fault the game for using a simpler ruleset that works just fine 95% of the time.
Think of Hit Points as your PC's 'plot hazard immunity' points. The less you have, the closer to a redshirt you become. Now watch any movie, or read any fantasy novel. The heros dont soak lasers to the face, swords to the neck and so forth. The blaster bolts impact on nearby walls, he dodges or parries the attacks at the last second, some lucky plot contrivance stops him from certain death, and so forth. Maybe an attack glances off his shoulder, letting us know that he is getting 'low on hit points'
As I said, that raises a whole bunch of other questions. If Hit Points aren't something that characters know about, then they can't use that as a basis for fleeing from a difficult combat, or asking for a Cure spell, or anything else. Your reward for jumping through hoops in trying to explain how you "weren't really hit" is that you get to keep jumping through more hoops to explain why you won't fight this
next orc even though the
last group didn't even scratch you.
In general, though, heroes of fiction soak plenty of hits. Look at Nolan's Batman, or the Netflix incarnation of Daredevil. When Frank Castle gets backhanded by the Hulk, he goes flying across the room and doesn't die. There's a huge amount of playable space between "that hit was actually a miss" and "that sword went straight through your neck". So what if 95% of all hits in the game are straight to the torso armor? Most hits
should be to the torso, from a probability standpoint. As long as a hit is actually a hit, and your state of health corresponds to your HP in some visible way, the game is actually
playable without resorting to an escalating slide of meta-game.
