Consistency in 4E?
So I guess that assassin just poisoned your morale?
And your luck is bleeding you to death?
4E is at least as inconsistent as previous editions because there is clearly physical damage in the game which still can be shouted away.
Fiction is rife with characters overcoming poisons through sheer force of will, and not medical intervention. Why shouldn't a Warlord be able to bolster that force of will?
Ongoing damage could easily logically represent growing fatigue or loss of focus, and Warlord inspiring his ally to take a moment to snap out of it. Just because HP
can represent Luck doesn't mean that luck must be a possible logical interpretation of any and all HP loss.
Also, bear in mind that just because a point of HP lost is physical, doesn't mean that points of HP
gained have to be physical. HP is abstract and represents many things. There's no reason a character couldn't start out a combat at full HP, with them representing 50% Health, and 50% Morale, and end the combat at full HP, but with them representing 20% Health and 80% Morale. Even 0 HP doesn't necessarily mean 0% Health; it could be 20% Health, and -20% Morale.
If you want consistency (I do) then you need either have only one type of damage (morale or physical) with no exceptions or a clear way to differentiate between the two types. (See the older Star Wars D20 for an example with Vitality and Wounds).
HP in 4E are consistently abstract. What you desire is concreteness, not consistency. Systems where HP are always abstract, and systems where HP always represent physical damage, are equally consistent. The former is simply more abstract than the latter.
The inconsistency in previous editions was that HP appeared to be abstract when it came to damage, but concretely physical when it came to healing. 4E treats them as consistently abstract (and as they've always been described), whether they're increasing or decreasing.
