It seems like the process went: "How can we reflect the Warlord's unique flavor in a combat ability? The Warlord should offer additional tactical superiority to his allies. It has powers that actually do that to the players at the table, by giving someone bonus attacks and additional movement."
Really?
To me it seemed more like the process for that went "We don't want the cleric to be the only healer anymore, and we define healing as a 'leader' role ability, and 'leaders' also include general character enhancements. Also, we like playing with minis, and we're making this in-depth tactical combat system, and we need a class to show it off. Lets make our new healer a tactical buffer!"
I don't think I'm alone in that perception, and, unless you've got some evidence to the contrary, that perception could certainly mesh up with reality.
And if it does, this represents a slight shift, at least here, in how the design is driven.
You position could mesh up with reality, too, but given how a warlord screaming at you doesn't give you the power to ignore wounds, but
actually heals HP, erasing the damage done, I don't find it quite as tenable, personally.
I mean, these designers are clever. If I wanted a warlord's scream to represent added endurance, I would, say, allow their "inspiring word" to increase the threshold for unconsciousness by healing surge+1d6 (or whatever). So, normally, you go unconscious at 0, but when the warlord screams at you (and maybe have a healing surge value of 10 and roll a 3), you go unconscious at -13 instead, giving you a few extra rounds to fight. And once the combat is over, and the adrenaline stops flowing, the buff wears off and you fall unconscious, showing how great of a toll the wounds still took on your body.
That's a little sloppy, but it at least actually mirrors the story justification for how the ability works. Right now, the ability doesn't.
Edit: Another possibilty would be to give temporary HP, or some sort of Resist 5 Everything, and it maybe could be keyed to the Bloodied status, because I am not sure how much more resolve I'll find in myself if I'm not feeling like I'm in much danger. Point being, there's a lot of ways to reflect that story, and the current method isn't reflective of it.
