And yet they want capabilities that work like magic, with a similar power capability, but aren't able to be interrupted in a similar manner... You see why that is a problem right.
Of course I see that as a problem, and it would be if that was what the
majority (not necessarily the most vocal) of warlord fans want. So let's take healing. Most warlord fans want abilities that allow for quick, in-combat healing, but most - much in the fashion of 4e - don't want its healing to be as potent as a cleric, bard, or druid's. But to play in support, you need a modicum of
comparative, albeit not equivalent healing abilities for certain situations in and outside of combat. The 0 hp debate often finds itself at the epicenter. And alternative methods of healing, of providing 'real HP,' have been proposed by warlord proponents (and non-proponents for that matter). One of my favorite suggestions was that the warlord could grant 'inspiration dice' - much as a bard - to players that operated as bonus HD that they could use for healing. It also alleviates a problem raised about the warlord inspiring on command or "I'm not inspired." Well, if you provide inspiration dice, then the player granted healing HD can decide when they are inspired to heal. Their subconscious could even potentially kick in telling them "to get up," or they could say that it's actually a non-warlord player who they heard getting up. "Inspiration" should not be equated to "admiration" when it may very well simply be "inspiration" in the vein of "artistic inspiration" or "something they said (unintentionally) gave me an idea." Roleplay that healing inspiration HD as you see fit.
I think many, if not most, warlord fans in these threads would prefer if the warlord provided more offensive support and alternative healing methods (e.g. granting resistance, imposing disadvantage, etc.).
(Also, I would not be opposed to having some of the warlord's abilities interruptible. In fact, I recall suggesting that some warlord maneuvers should even require concentration to maintain and operate the same.)
