When I use the term rapid, I mean turning wounds into something other than injuries so that you can recover them after a short rest.
I don't want non-magical healing to go beyond what was normal prior to 4e for narrative / versimilitude reasons. Nothing to do with functionality.
I don't mind myself. I'm not looking for realism and D&D isn't real and shouldn't be heavily interested in realism either. Some verisimilitude is nice. But I want it to feel like a fantasy story. It is very rare that lasting wounds limit the heroes in fantasy stories. It is very hard to write a story realistically with a person with serious wounds being effective. If your wounds are of a serious or debilitating nature, you would be laid up for long time were the game to focus on realism.
I was pleasantly surprised with the long and short rest mechanic. Unless I'm trying to play in a gritty, realistic system, anything but death is minor and should be recovered from quickly. You don't see Gandalf, Aragorn, Conan, or the Arthurian Knights permanently crippled in standard combats. The only time they suffer serious hurts is if the story calls for it and usually from unusual means. D&D is high fantasy and not meant for gritty realism. Plenty of other games do that part of wounds better.
