Similarly, it's disingenuous (at best) to present Schroedinger's Wounding as a drawback to 4E that doesn't require a constant barrage of fruits & veggies (in the form of working to avoid it) to solve.
I'd say that it takes a constant barrage of working to CREATE the problem, in the form of assigning impossibility to occurrences which the game itself does not declare or hint at being anything other than the status quo.
The game itself never states that for the protagonist heroes in its epic fantasy world, healing from any wounds short of fatal ones is not achievable by seemingly non-magical effects, or that it cannot happen in periods of time which would seem amazing in our non-fantastical real world.
The rules seem to support the opposite view, in fact. Thus, the game itself isn't creating a logical inconsistency or a gap in internal realism. It's just presenting a world which is apparently a bit TOO magically adventurous for you. The only contradiction, the only conflict which requires all of this "constant working" you refer to, is overlaid onto the game from the outside, from the pre-conceived ideas of gamers.
I have a pre-conception that people absolutely cannot shoot fireballs out of their hands. All of my experience agrees with this, therefore any world in which people CAN do this is obviously unrealistic. So if a game appears to allow for this absurdity, then the GAME ITSELF must be broken, and I need to "constantly work" to reconcile this disconnect so that the game world makes sense to me.
That sounds silly, right? Well, have you considered the possibility that you're doing the exact same thing?
You have the same pre-formed idea about how quickly and under what circumstances a wounded fantasy hero can heal physical injuries. The game doesn't support your idea, though, in rules OR in descriptive text. You're putting that contradictory concept into the game, yourself, and then saying that the game itself has this inner flaw which causes a narrative/gameplay disconnect. But it's your imagination, not the game.
Just accept the premise that the game itself clearly indicates, which is that real healing can come from a variety of sources, many of them not overtly "magical" in an Arcane or Divine sense, and that a protagonist HERO in this fantastical world can, in fact, be savaged to death's doorstep today, and be healthy as a horse tomorrow, even WITHOUT the glowy hands of a cleric getting involved.
All the problems go away at that point.
