As in 'Hero' could be a name for a class.

OK, a very broad class, like Fighter, Rogue, & Warlord - and Paladin - all wrapped together.
My issue isn't with taking one hero from history/fiction and saying, "That's a Warlord." My issue is with taking nearly all the heroes and saying, "Those are Warlords."
D&D does have a problem modeling heroes of myth & legend - and genre. No small part of that problem is the very limited set of abilities it's traditionally given the fighter and rogue, the only candidates to model most of those heroes, because casting spells and other feats of magic isn't exactly prevalent among them. A lot of heroes were great leaders in some sense, or cunning in some other sense, and the traditional fighter class consistently failed them.
5e /could/ have dashed off the Champion as the traditional fighter, left most of it's DPR baggage in that sub-class and gone off and done some things more interesting than the BM & EK with the rest of the class. It didn't, and the way it didn't leaves a need for an entirely new class. The Warlord is the remaining PH1 full class that hasn't been done by 5e, yet, and 5e isn't constrained by Role the way 4e was, so it could be stretched to cover quite a bit more than just support.
On a meta-note, although you are usually quite reasonable in your posts, I do notice that you don't seem to grant a single iota of validity to any of my concerns.
I think you did express a concern or two perhaps a single iota of validity, and I did address or acknowledge them as such. Balance isn't an invalid concern, for instance, just not a very relevant one in the context of 5e, where class balance is an after-market accessory installed & maintained by the DM.
But the kefluffle over the name when each objection to it is as or more cogent to other class names already in use? No iotas there. Sorry.
Ok, over lunch I thought about a "Warden". Curious if Warlord fans would like this class.
Even before it was a 4e Primal Defender, I'd used the name 'Warden' for a Ranger variant in 3.0, so the name has extra baggage for me, even beyond what the turning-into-a-tree-or-whatever version established.
That's certainly a strike against it, since you can't comprehend the appeal of the Warlord in the first place.
Medium or Heavy Armor (all the same to me), Shields, Martial Weapons

MAD: Dex or Str, Intelligence*
*Descriptions of this class seem to rely on both Cha and Int.
Yes. Both INT & CHA should be there. Really, there's a case for WIS as an alternative to either, as well.
For a variety of reasons, including existing design space and trying to get away from the "Leader" concept, I'm leaving Cha totally out of it.
Strike 2. Like taking the STR option away from figthers - yeah, DEX fighters are cool and all, but the original kind need to stay in the game. Plus, avoiding or playing the 'Leadership' possibility of high CHA is something that can be left to players to figure out. Anyone with high CHA, let alone a background like Noble that implies authority, might be RP'd as a party-leader, or not. Mechanics that support using CHA to aid allies could be visualized as leadership, or cheer-leading, or even emotional attachment inviting rescue. It depends on what works for the players in question.
Abilities (rough sketch, not sure of order)
- If within 5' of an ally can use reaction to grant advantage on attack roll, saving throw, or Concentration check, or otherwise use Help action.
Help is a universal thing, and Advantage looses steam quickly in 5e because so many things grant it and it doesn't stack. Still, like the Mastermind's enhanced help, it's a neat little idea.
- If within 5' of an enemy can use reaction to impose Disadvantage on attack on somebody else (not self) or prevent an AoO on somebody else (not self)
Very similar to protection style.
- At 5th level, gets two reactions/round (instead of second attack)
Interesting, possibly alarming as it actually does mess with the action economy.
- Use Dex + Int for initiative, and any allies can choose to use your Int bonus instead of their own Dex bonus.
meh.
- As an Action grant scaling bonus HP to all allies within 30'. Int modifier times/short rest.
Not terrible, a little odd for INT, but not a suitable replacement for restoring hps.
If able to prepare for a combat for at least one round (before Initiative is rolled) and communicate with other characters, grant Inspiration to everybody.
Which Inspiration?
