I'd say that the warlord isn't necessarily as militarily hierarchic as you have painted him. It's probably the easiest and most obvious way to conceptualize his abilities, but it isn't the only way.Because giving orders implies a military hierarchy on the concept of the adventuring party (an unforgivable trespass on the nature of fantasy heroes), and trivialises the expertise of the other heroes by assuming that the warlord is somehow more expert than they are in their chosen field. Singing, praying and spellcasting don't imply this.
A warlord could be:
1. A scrappy kid that inspires through his natural optimism and enthusiasm.
2. A cool-headed thinker with a knack for analyzing the tactical situation and spotting opportunities.
3. A grim, battle-scarred, threat-spewing warrior who unnerves his enemies (or occupies their attention) so much that they make mistakes which his allies can exploit.
When you boil the warlord class (and, in fact, all of the Leader classes) down to its most basic concept, it's that of helping others to do better. Shouting orders and telling people what to do because you know better is only one way of doing this. It isn't even the only non-magical way of doing it.
