Until a low magic campaign without a god-botherer or healbot is practical it will fall massively short. Or do fighters restore characters HP up to their full value now? The expectation for the Warlord is we do not need a cleric in the party. And we do not need spellcasters to keep going - we don't have to play a high magic campaign. And Mearls is explicitely opposed to this, making quips about shouting hands back on despite the fact that's way outside the Cure Wounds territory. (No one is arguing Warlords need a Regenerate equivalent, merely being able to handle the normal rigors of the adventuring day).
Without inspirational healing the Warlord can not fulfil its metagame role. And we revert to the narrowness of settings and worlds that all previous editions of D&D enforced (yes, even 3.X). Without the Warlord we are effectively limited to worlds where spells can be cast almost instantaneously, and where even a third level caster uses far more magic than Gandalf. Yes, there are other ways than the Warlord class to do this - but Next isn't offering them either.
I'd be more than happy to talk about this in a thread about it, but I'd prefer not to de-rail this one. I think the ways in which the current fighter options meet or fail to meet the needs of warlord players is a good convo to have!
That solves the tracking spell components. The silly spell components are a separate problem.
I'm implying that it can be solved by going abstract. If all you need to use a spell is a "component pouch," you can safely ignore the silliness -- wizards at your table won't be twirling nuts in their hands to cause madness, they'll just be reaching into their component pouches and waving around some incense or whatever.
