I didn't say the spec's abilities represent it but, according to my analysis, it is very much one:
The Mountain King's official description
"The mountain kings, or thanes as they are known in Khaz Modan, are the mightiest dwarven warriors under the mountain. Wielding both enchanted warhammers and hand axes, these fierce fighters live to test themselves against worthy opponents."
My race/class combos thread

Dwarves had the racial abilities "Gun Specialization" and "Mace Specialization", which increased Guns, one-handed Maces and two-handed Maces weapon skills, respectively (and then Crit and, lastly, Expertise before their removal). While Hunters, Rogues and Warriors could all wield Guns back in the day, Hunters could not (and still cannot) wield any kind of Maces and Rogues could not (and still cannot) wield two-handed Maces. that leaves us with the Warrior class. So, which spec, exactly, fits the Dwarven Warrior? the Fury Warrior does - as the Mountain King dual-wields a Mace and an Axe (i know the Warrior class cannot wield Guns anymore and the Mountain King does not utilize Guns, but it could still benefit from the racial back in the day). Moreover, their racial "Stoneform" (sometimes refered to as Avatar) resembles the Mountain King's "Avatar" ability, as they both transform you into stone (in HotS and Warcraft 3, at least).
The spec's description
"A furious berserker wielding a weapon in each hand, unleashing a flurry of attacks to carve <his/her> opponents to pieces."
You seem to forget that the, very much, iconic Berserker Stance of the Warrior class depicted a Dwarf:
The Mountain King may be a Thane, but it is far from a noble. The Dwarven Warrior archetype is, typically, based off of Nordic/Scandinavian Warriors:
Moreover, Barbarians are not exclusive to Orcs:
"Wildhammer dwarves are renowned for wild behavior and deadly skill at arms. They have a tendency to enter a fray armored with little more than a loincloth and body paint, and still come out covered only with the blood of their foes. They are fierce charging across the ground or when soaring atop gryphons; barbarians of other races seek to emulate Wildhammer dwarves' reckless ability to stay alive through sheer pluck while laying waste to their enemies. The iconic Wildhammer barbarian clutches his hammer and grins, showing gaps in his teeth. Feathers and beads are stuck in his sweaty hair and beard. "Come get some!" he shouts, before letting out a howl and charging forward."
Granted, the Wildhammer Barbarians are not the Bronzebeard Mountain Kings, yet they are both Dwarves. In Shadowlands, only customization options separate between the two.
If you look at their tattoos, they very much resemble those of Sonya, the Barbarian:
And she has abilities and talents like Fury, Wrath of the Berserker, Furious Blow, Shot of Fury, Battle Rage, Ruthless and Rampage.
The abilities of the Dwarven Warrior, like the Mountain King and the Gryphon Rider, are very lightning-based, due to the real-life Thor beliefs equivalence of Scandinavian/Norse people.
The Death Knight hero unit, although it doesn't use any Frost abilities, is based off of Arthas. Therefore, i would categorized it as a Frost Death Knight, more than anything (not a tank).
The Tauren Chieftain, i would say, is the closest to an Arms Warrior, according to my analysis:
Tauren have the racial ability "War Stomp", which is based on the Tauren Chieftain Hero unit ability "War Stomp" from Warcraft 3. now, their description says: "These elder Tauren warriors lead their Tribes in daily life as well as in battle". the WoWpedia page says they could be either a Warrior or a Hunter. they had the Shockwave ability, which was given to the Warrior and the Reincarnation ability, which was given to the Shaman. Their racial ability "Endurance" increases stamina, which is helpful for tanks, but used to increase base health only. their "Brawn" racial increases Crit damage and healing, which benefits dps and healers. The lore states: "Being great huntsmen and natural wanderers with a certain natural affinity, the tauren developed a deep knowledge of the botanical life of Azeroth, using it in various shamanistic rituals, as well as for medical treatment" - which implies that they are Hunters, Shamans and even Resto Druids. Furthermore, "Hunting the kodo and wandering the wilds has not been easy for the tauren, and facing the centaur has made it no easier. All tauren are born with the ability to communicate with the spirits in times of need, beseeching them to shake the earth and stun their enemies." - which, again, implies on a Hunter or Shaman direction. And yet, i feel that they are neither of these. the Tauren Chieftain unit uses a two-handed Axe and not a shield which means that they are not a Protection Warrior. That leaves us with Arms warrior, Survival Hunter or Enhancement Shaman. The survival hunter is, already, taken by the Troll race, and none of the abilities of the Tauren Chieftain is a Hunter ability. The Enhancement Shaman would be possible, as the Tauren Chieftain unit has the Reincarnation ability. But, the "Axe of the Tauren Chieftains", an item dropped by Baine in the End Time dungeon has Strength on it, which benefit Warriors, Paladins and Death Knights rather than Shamans or Hunters. Furthermore, Cairne and Baine, both Tauren Chieftains, are depicted in-game as Warriors - having Warrior abilities like Mortal strike, Cleave and Thunder Clap.
Blademasters are closer to an Arms Warrior, than a Fury Warrior:
"A battle-hardened master of two-handed weapons, using mobility and overpowering attacks to strike <his/her> opponents down."
"Blademasters, also known as blade masters, are legendary orc warriors of the Burning Blade clan, known for their mastery over swords, axes and polearms." (two-handed)
Troll Berserkers are an upgrade of the Troll Headhunter (Spearthrowers), which are set apart from the enraged melee Warriors:
The Troll race have a racial ability called "Berserking", which is based on the Troll Berserker unit from Warcraft 3. The unit is an upgrade from the Troll Headhunter unit of Warcraft 3. their description reads as follows: "These cunning warriors are trained from birth to hunt, track and trap the most dangerous beasts in the wilds". It matches the Survival Hunter old description: "a rugged tracker who favors using animal venom, explosives and traps as deadly weapons". In addition, with the Legion expansion, Survival Hunters, once again, use melee weapons like Polearms, which lines up with Troll Headhunters using Spears. They even had a glyph called glyph of the headhunter: "You throw a javelin instead of a hatchet when you use Hatchet Toss" (yes, i know rogues had one too: "Your Throw and Deadly Throw abilities will now throw axes regardless of your currently equipped weapon" - which, essentially, turned you into an Axethrower not a Spear thrower). Now, as for their racial "Beast Slaying", the lore says: "Trolls are excellent hunters and have developed skills in [Beast Slaying] over thousands of years". Furthermore, they had racials called "Throwing Specialization" and "Bow Specialization", which increased weapon skill with Bows and Throwing Weapons (and later on Crit before their removal). The only classes who could use them back in the day were Hunters, Rogues and Warriors. the lore says: "bows and throwing weapons are the iconic arms of the troll race, and has led to troll headhunters being one of the main forms of ranged support for the Horde".
Feral Worgen aren't Warriors at all:
"Worgen warriors are likely common as the kingdom of Gilneas had many footmen and knights. Unlike the half naked wild worgen who fight like animals with teeth and claws, the Gilnean worgen fight like men, wearing plate and mail and armed with steel swords and polearms."
The Orc Barbarian would pass as a Fury Warrior, yes. Embracing their demonic bloodlust and dual-wielding axes.
Hellscream, on the other hand, wielded a giant two-handed axe (Gorehowl). as i've, already, shown, it matches the Arms type of Warrior:
"The iconic orc warrior is garbed in chain mail or leather and plate. He carries a mighty battleaxe and wears a horned helmet. He crouches in a battle stance, axe at the ready, as he evaluates his opponent...then, with a fearsome yowl, he strikes in a blur."
It would only steal Bladestorm from the Warrior and Mirror Image from the Mage.
Demon Hunters stole Smoke Bomb from Rogues? What?
