I'm a fan of multiple mechanical models for most things.
Except apparently when the Warlord class is one of the options.
I'm guessing by "panic button" you mean specifically a big spike recharge of HP?
Yup.
You could have each character carry their own panic button (fate points, second wind).
So now we have non-magical healing. Also this fails because it can not be used on someone who is down. (At least without changing the fundamental nature of being down).
You could have an environmental/circumstantial panic button (kill the orc, get HP back).
You need the panic button for when things are going pear shaped. "I'm panicking ... because I've just killed an orc". Nope.
You could have a panic button based on time (everyone gets a big HP burst after 4 rounds!),
Cue @mearls making jokes about hands spontaneously regenerating.
or a panic button that triggers with a given event (an ally drops below 1/2 hp). There's infinite ways to hit that button.
I doubt it's infinite. But there are a lot. How many of them have actually been tested to work? Because the Warlord has.
You could also have a panic button in the form of a mechanically-identical defensive buff. You can ignore X attacks, or gain X temp HP. There's a lot of different forms that button could take.
You could also not have a panic button.
Re-read my OP. And not needing a panic button makes combat flat, and completely lacking in tension. Which ... if that's the sort of thing you like. "Having less magic makes the combat less tense." Right.
You could mix and match or combine all of these kinds of abilities, traits, mechanics, and tricks. Each one has its own different feel and style and psychology.
And right now you are just throwing out a handful of frankly ill-thought-through ideas, and certainly non-playtested ones. All so we don't get D&D Next contaminated with the Warlord class. There might be lots of options - but the option space of those that don't work is far, far larger than that of those that do. And why are you working so hard to reject the Warlord and the idea of inspiration to greater feats from a martial character?
Take a look at what Guild Wars 2 does with healing: there is no class that will keep you alive with HP recovery. While support does exist, support doesn't take the form of counter-acting enemy damage primarily, which means each player must actively dodge and predict and pre-empt. What healing there is mostly is distributed to the individuals, to heal themselves as appropriate.
And Guild Wars 2 is built that way from the ground up. D&D has a panic healer, and as I pointed out in the opening post, if you have a panic healer unless they are utterly anaemic they are always going to be superior to precautionary healers because they get to apply the response where it is needed.
To me, D&D5e seems to be on-track for allowing a lot of different kinds of defense and recovery as appropriate to the given genre, playstyle, and setting. The panic button being in one character's hands is one way to do it, and that's suitable to the D&D cleric, but it's not always suitable beyond the D&D cleric.
Except that the inspiring warlord who gets people on their feet is appropriate to many genres, playstyles, and settings. And far more than the Cleric is. You are, so far as I can tell, arguing that D&D should not have inspiration able to get people onto their feet because the range of genres in which inspiration is not applicable is larger than those in which it is combined with those which it isn't and you drop the Warlord class.
Right.
By default, we'll probably have a cleric with a panic button, because that's very "D&Desque." But that's the beginning of the story, I think, not the whole story.
Of course we will. And if D&D actually cares about diversity rather than being the cargo-cult design it appears to be, we will also have a warlord with a panic button. As well as other options that ignore the cleric or the warlord.
Why are you going to such lengths to propose methods that have almost never been done in D&D while rejecting out of hand one that has and that works? I.e. The Warlord. It certainly isn't a wish for diversity. Or for genre emulation. Because adding the warlord as an option increases both and is a whole lot simpler than the other solutions you offer.
I don't think the Warlord is a good solution to the no-healer campaign. It just goes from "we need a cleric" to "we need a warlord." It's the same problem with a different coat of paint.
The Warlord isn't a solution to a no-healer campaign. It's a solution to the "We don't want Divine Vancian Casting" campaign for whatever reason. And the 4e Warlord doesn't actually heal. Actual healing in 4e is surgeless healing.
(The difference between the Warlord's Inspiring Word and the Skald's aura for this purpose is largely academic).
@Jester Canuck , why is there a limit on inspirational motivation? Because bodies can only take a certain amount of punishment. And people get fed up of hearing the same sort of speech over and over again.
Edit: [MENTION=21178]Szatany[/MENTION], that's roughly what 4e does. It just calls wounds Healing Surges - although it doesn't provide a penalty for losing them.
