You know, I've always wondered why people complain about the Warlord's Inspirational Word power as if it is somehow inconsistent or unusual. It isn't. It makes perfect sense within the context of 4E as a whole, and given the way HP damage and Healing Surges work in that system.
In 4E, the natural tendency of damage is that it goes away on its own given enough time. Any amount of hitpoint damage will be healed automatically at the end of battle during the typical five minute short rest (given there are enough healing surges left over). Every character can use a Second Wind once per battle to heal themselves almost as effectively as they can be healed by a Warlord, Cleric, or Bard.
In fact, it is easy enough to say that, in 4E, the main forms of at-will Cleric healing are no different from the healing provided by the Warlord. Both are "Word" powers that depend on triggering the healing surges, the innate ability of a character to heal themselves. A Cleric's Healing Word can be flavored rather naturally as a spiritual morale boost, rather than as an act of miraculous injury-removal. A Cleric needs to use a Daily Power in order to perform anything that is flavored as actual miraculous healing (Cure Light Wounds is a level 2 Daily Utility Power, not a basic healing technique).
So, if a Cleric and a Warlord are quite literally using the exact same method to restore hitpoint damage, and such healing works to a limited extent for every single character, why is it problematic only for the Warlord? Why is it the Warlord's problem?
Anyways, I guess the whole point of this is to say that I both like the Warlord as it exists as an independent class (though I'd be fine with it being called the Lord), and just as importantly I like the entire system of healing used in 4E, which helps justify the Warlord and removes the game's dependancy on magic for healing seen in older editions. It works for me, and I'd be really disappointed to see it go away.
