Not really no, engineers can make anti-grave devices, SO i’m assuming it’s 100% tech coming from a Gnome.
By replacing limbs and stuff… that’s cybernetics.
Goblin/Gome town in a box, again I’m assuming this is tech due to Gnomes/Goblins.
They do though, we’ve seen factories/companies before.
I know I’d be nervous the first time a dwarf popped stoneform in our hypothetical war.
But my strategy is to offer them some of the fantastic Earth beer. Brewing technology has come a long way in the past 200 years, while Azeroth’s beer has lagged behind. Probably.
This is all assuming that Azeroth gets to keep their universal physics when crossing into our universe with vastly different physics in place.
And if they do, there is no rule stating that Earth would not be granted the same and can not use the new universal physics with our own natural. Allowing us combined power with our technology.
I’m genuinely not sure how well we’d do with the sudden application of whacky cartoon physics.
I’d contest that. Each new expansion is coming out with new local drinks & food. Not all are beer, but there’s enough to make me think they’re still trying different techniques. Or at least importing from other dimensions, which is fair.
Look the United States is constantly at war, you all just don’t see it or hear about it.
There is like 250 nations on this planet and a crap ton of Spy Agencies, terrorist organizations that constantly fight a silent deadly war among each other.
Earth would wipe the floor with Azeroth, politically, economically and militarily, a no contest and I would bet my entire life savings on it.
introduces the ability to look like anyone or anything as well as the ability to detect such illusions among many many otherwise unknown methods of espionage
“I’ll take your life savings now.”
Azeroth doesn’t seem to have the focus on hops breeding or food technology, not to mention modern hygiene protocols.
I’m not sure who’d win in a dustup, but I’d back our beer!
Lol. The Alliance best investigators, spies and assassins didnt even know that Ony only used a tiny bit of magic, just to be in a human form and just play simple high school politics to plundge Stormwind into chaos.
But time-travelling dragons.
But it’s AZEROTH vs earth, so that includes Horde… as well as unaffiliated factions… the Twilight cultists for example count as part of Azeroth.
Who would need to know the history, and agencies and teams as well location to infiltrate, and to get such knowledge, they would have to be ready to interrogate millions in hopes of a sliver of knowledge.
And is that accurate knowledge and not pathological crackpot conspiracy theorists playing pretend, despite them believing they are the real deal even if they are not.
A handful of Deadlords take over Social Media and politics. The earth destroys itself in less than a week.
Moving the goal post now huh? So, every being from Azeroth gets all its universal physics and instantly knows all of earth’s history and governmental intelligence.
My, that reach is making Inspector Gadget blush.
That’s interesting, but not all beers are made of hops. Lotta ancient beers were just unmalted fermented grain (wheat, barley, oats) and flavored with herbs like heather or mugwort. We don’t really see a lot of ‘traditional’ grain in the game, unless you’re in Westfall, Valley of the Four Winds, or let’s see… I think Stormsong. Those are farmed. Wild grasses are often grains though and we have no idea what edibility they’d hold.
As for sanitary practices, I’d reckon a mage or other elemental caster could potentially just blast the area and destroy microbes. Arcane magic seems like it’d be the most relevant for that task - like microwave radiation, just sizzle everything inside and outside so it’s sterile.
Our one advantage is that per our knowledge, we have a way broader understanding of which of our plants are consumable. Maybe Azerothians do too, but we’re only introduced to a few ingredients via game mechanics.
I think we’d go neck and neck on the war of beer vs. Azeroth. That’s a way better war to have anyways. 
Azeroth never see a nuclear warhead go off. If even a single 100 Megaton warhead went off it would make turn the Jailor and all his minions crispy critters. Azeroth never had a Albert Einstein so Azeroth has never seen explosions of this magnitude.
I think Earth would win by sheer overwhelming numerical superiority.
That already happened in 2016. Didn’t work.
