I think we should try to separate the 4e warlord from what we want of the 5e warlord. I'm okay that in 4e, the warlord was a healer, but what if, maybe, in 5e he was to do something else? Some people also argue that having a warLORD at level 1 makes no sense, like having a lvl 1 mage called an archmage. So I think the class should have a name that reflect this power progression (lets say Marshal, with the capstone being called Warlord), and have archetypes based on being better prepared for battle.
I can see the last rogue ua's scout as being an archetype for the stealthy ''marshall'' (help you party land an ambush).
I can see an archetype of battle field healer, loosely inspired by the master healer from AIME.
I can see an archetype with shouts that works as auras with different effects.
I think it should heal, and be named a warlord. The coremost reason of the warlord for existing -from a certain perspective- is to be a nonmagical cleric replacement. It must not use magic, it must replace a cleric and it should be named warlord. If it doesn't do any of these it is a waste of time as it wouldn't be any better than the PDK/BM/MM.
Maybe they should design the class and then put it with an Aaracockra-like disclaimer. But it oughta heal, and it oughta be non-magical and it oughta be called warlord.
