Uhh... I've posted 15 counter-examples. One person argued that Frodo's covered under a disease mechanic and you've argued that John Constantine's lung cancer doesn't count (because he gets his ass kicked when he's healthy too?). But it's hardly 10-2... if you want to win the thread that you posted, rather than actually engage in an exchange of ideas and data, for some weird reason.
If you, as the OP, are going to ignore people who respond to your direct question, then you should have made it a blog post. That's where monologues go.
Sorry about that. Took a long time to post my reply and didn't see your points. At the time of my posting, I saw things at about 10-2. My bad. To be fair, I also didn't even SEE your stealth posted examples. Does it really count as spoilers to a show that's been cancelled for years?
Then again, how many times are Buffyverse characters beaten up, kicked around, whatnot and then just press on afterwards. Every single one of your examples are plot related. If there was no plot reason for those injuries, they would never happen.
But, here's another example. Someone mentioned Wesley from Princess Bride. Here's how you do that with 4e healing mechanics:
First, the Raise Dead ritual would have to be changed slightly. Instead of bringing you back full, it brings you back with 1 hp and no rest. This could easily be accomplished because Inigo doesn't actually follow the ritual correctly.
Second, the Machine sucks out Healing Surges. When you run out of surges, it sucks out hit points.
Now, when Wesley is killed by the Machine, he dies with no surges. He comes back later with exactly 1 hit point and no healing surges. If he rested a day, he'd be good to go, but, there is no time. The Wesley player role plays the fact that he has 1 hit point and he dies if someone sneezes at him. But, at the proper moment, he stands up straight and bluffs Humperdink into surrendering. He then also jumps out the window and rides off into the sunset.
Done.
As far as "but, but, but, it will happen every fight" goes, well, that's ridiculous for several reasons. One, you have limited healing surges per day, so you simply cannot have it happen every fight. Two, you are not going to get that hurt in every fight that it would even need to come up. Three, the only way it would come up is if the DM and the player both decide to narrate the action in the most ridiculous way they could.
