I think Alterac’s biggest problem is that it was pretty obviously put into WoW as an afterthought. It’s a tiny area - one castle, one small town, one road between them, that’s it. Even if they rebuilt everything with new assets, selling it as a “reborn kingdom” would be hard. Its smaller than Westfall.
Having it remain as this… empty, ruined place is probably a better use of the space, honestly.
Like with a lot of things its how you use your space, right? That said, my intention for it and all zones is to really supersize them, bring greater size and depth to the world as a whole.
It would still be on the smaller size, perhaps, but if we’re talking about a zone we quest and experience story in, X by Y size doesn’t really matter any more. Blizzard has the technology for flash backs and instanced quests, vertical terrain, deeper more expansive caverns, and urban gameplay. You also have the entire Uplands which has been criminally under utilized except by literal criminals. Its this fairly large and open area that hardly a quests send you through and that says nothing for the coastline to the north of the zone, or even stealing the fingers back from Hillsbrad.
So its workable, just might need a little imagination
Alterac is interesting because as it stands almost all the ruling class went entirely off the reservation and became Syndicate, though I wouldn’t mind seeing it restored in some capacity. Building up the various groups of all the races again would be nice, Stormwind shouldn’t be the end all for human stuff.
I would prefer it to be a Horde zone ruled by ogres! We need more proper ogre cities!
I think Alterac Humans as an allied race for the Horde would probably be a good thing. Mostly because, since lore development leans toward humans, it might help stop Blizzard from ignoring the Horde when a faction conflict isn’t involved.
There’s also the issue of it being located pretty close to Horde Central.
At this point it would be Alterac Ogres.
There might actually be something there. TFT calls the clan Rexxar takes over and the clan Sylvanas takes over both “Stonemaul,” despite them being on different continents.
To be exact - the Crushridge (The Ogre clan that occupies Alterac) is a breakaway faction of the Stonemaul Clan.
Presumably that could be remedied by, Ogre politics being what they are, having a Stonemaul Ogre (or Rexxar) going in and beating the head of the Crushridge to reunite the clans.
Always thought Alterac would have made a better forsaken kingdom rather than Lordearon. I mean they joined with the Horde all the way back in warcraft 2, they have a similar aesthetic as the forsaken and had been at odds with many of the other alliance kingdoms for years.
I’d be fine with it remaining the only destroyed perma-destroyed human kingdom. Not only were they traitors to the Alliance but they were also just dumb if they thought the demon fueled rage berserkers who charged out of a portal and destroyed Stormwind, with warlocks, death knights, and enslaved dragons, wouldn’t turn on them once the other kingdoms were taken care of.
If there are two races that should never cross over factions lines, it’s Humans and Orcs.
It would be one easy scene for Blizzard to have a place in there with humans who drive them out or something.
As per Tides of War’s ending it is not doing that. That the arcane residuel(if there is still any) has no effect. And certainly no eternal fire. Hell, Varian even wanted to turn it into a Garrison at the end of MoP.
Yes it does.
That is the point. The reason Garrosh attacked it back in the day was precisely because without it the Alliance could not easily reinforce the night elves. Which Sylvanas effectively continued his war. Rebuilding Theramore would mean the Alliance would once again have a second main presence to quickly help the night elves.

Varian’s wishes mean nothing considering it’s impossible to rebuild Theramore. How is he going to turn a crater into a garrison? And as for the effects of the residue?
Alliance and Horde forces scouted the ruins of Theramore to assess its viability as a base. Among them were Instructor Duskwalker and Magister Zaedana. The effects of the mana bomb still lingered.[38]
The effects of the mana bomb are still lingering.
Yes it does.
No, It doesn’t.
Because for the most part it is not a crater? Two, the Alliance has filled an entire crater before to make Lion’s rest. Three, we have literal magic that can do incredible things. Filling a hole in the ground is actually pretty easy in comparison to some of the Alliance have built/rebuilt.
I’m not sure how canonical that is. But even then I think any lingering effects are minor at best, especially considering you do suceed in those war campaign missions.
Yes it does. And if Blizzard is planning on rebuild another human nation, Theramore should be in the front of line and Alterac, if at all, a distant second.
It kills me that the current creative heads lack the nuance to even consider this.
They probably think “Nah politics won’t interest anyone”. Meanwhile Game of Thrones was a whole darn thing.
Arcane Elementals merely need to be tamed. The Water from the Water Pipes running through the Arcane Rich Ground may become addictive which could result in a Nightborne-esque scenario if the Humans spend too much time in Theramore.
It would be a lot more creative to give Horde players the ogres they’ve been asking for this way. We don’t need every single Human kingdom back from its deserved grave.
Honestly, it’d be nice if they stretched the world continents and inserted quite a few of the literal battlegrounds & a few more various architectures + terrain stuff of their various themes into the world at their respective locations.
Having Alterac Valley and Warsong Gulch alone, as zones you could visit would be cool. 
I’m honestly surprised that Blizzard decided to give the Forsaken the Undercity back and didn’t just make a new Forsaken themed capital in Alterac.
