I'm not entirely sure that matters. Who cares what the intention of the designers was when they did it, so long as it works? They don't say one way or the other really, so do whatever works best for you.
When I said "ignoring the rules" I just meant that if you're critiquing 4e's HP system you have to take the whole thing into account, and not just parts of a whole.
I could argue that the rims on a car are a horrible design because when they travel down the road they spark and bend up... But that completely ignores the tires being a part of the system.
Well, that's something, glad I could help... kind of?
Yep, my guess is 4e is designed with the idea that the majority of players want to emulate things like TV shows and movies.
But something else occured to me on the train last night heading home from work...
You mention smart play indicates the player should ignore the wounds his character has narratively, in favor of pressing on since he's at full HP.
Isn't that skirting on, if not entirely meta-gaming?
If you're assuming the character is still wounded despite what his HP tally says, isn't the player then acting on information that the character does not have? The player knows he's at full HP, but the character knows he/she is a mess of wounds.
Similar to a player knowing a silvered weapon works best against a lycanthrope yet his character has never encountered one. Isn't it meta-gaming to act on that knowledge?
Or are you froma school of thought that there is no meta-gaming?
