Just North Western Kalimdor actually.
Night Elves lost claims to other areas long ago. Hell, not even Feralas is interesting to them, since the only night elf presence worthy of note was that wailing ghosts from Dire Maul who had been killed by Tortheldrin and later, the Horde.
There are still Horde Strongholds in the woods of Ashenvale are there not?
And still Night Elf strongholds dotted around Azshara and Feralas?
Morshan rampart was taken. Also Alliance has a presence in Durotar and Azshara. Places they have no business in. If we want to talk about fairness then the blue team should withdrawl all their forces from Horde core territory.
It’s simple.
Night Elves move to Hyjal and Winterspring, with Darkshore as a questing experience for Alliance (like Duskwood) and Ashenvale remains contested.
(Personally, Darkshore would be great for a second chance of Kaldorei vs San’layn - I was skeptical about whether that would work in BFA, but I really loved it. Kaldorei and San’layn are the antitheses elves and their conflict was far better than night elves vs blood elves and/or nightborne.)
Does not seem too bad, it would be good to see Winterspring in our hands
Darnassian hold over Ashenvale was always rather tenuous given the amount of Satyr and such, especially in the eastern parts. Zoram’Gar Outpost is wierd, because it’s existence is more of a gameplay concession than a story beat so whenever it pops up it’s a bit odd. But given the current state of things, if the Horde stays out it’s more of Horde restraint than the Darnassians being able to do literally anything meaningful about it.
Moonglade could work, but I think that’s a bit too “Druidic” to the point where Night Elf Hunters, Mages, Priests etc - it doesn’t really work.
Winterspring and Hyjal would work.
It would also be good to see both core Elf races (Night and Blood Elves) be the only two elves would command their founts of power.
I might play a Nightborne, but I do think the Night Elves and Blood Elves should have something more than their allied race counterpart.
I dont think Moonglade would work, because both Alliance and Horde druids are welcomed there.
I would surmise that the ideal world for Darnassian territory would be the territories surrounding Hyjal, which have geographical boundaries. Winterspring, Darkshore, Felwood, Western Ashenvale(Basically not the part directly north of barrens beyond the rivers) and the Wintershore(not actually in game)
Desolace is mostly under the Centaur Kahanate and Stonetalon doesn’t play to their strengths making anythign south of that unlikely.
Genocide isn’t really the Night Elf MO, even if they did have the forces to spare, in terrain that plays entirely to the strengths of Centaurs and not in the slightest to the strengths of Darnassians. Not to mention that enraging Cenarius would be the last thing. on the Night elf to-do list.
I am the future of the Horde. I will make the faction great again.
Actually that was the meme of Garrosh back then, they even made him wear the same hat of Trump in some images, with “Horde” instead of “America” 
For Winterspring, I don’t think the Night Elves (just like the High Elves who changed the climate of Quel’thalas in an eternal spring) particularly like to live in a snowy environment. The snow and cold kill trees, most animals and nature during winter after all. Yes it’s still a forest, but the snowy and wintery environment do not really fit the themes of the Night Elves (Shen’dralar included). Some Night Elves can live in Winterspring but they should be a minority, not a major concentration like it would happen with a new Night Elf tree and capital grown in that region. (also because the Goblins are already living there in one of their towns and we know they are not a race that really works well alongside the Night Elves)
Unless Tyrande renames the race into “Snow Elves” (or Falmdorei), hoping that the ones in Skyrim and ESO don’t get mad for this reason though 
(although I think they are mostly extinct)
Well I will make it true. The Horde will prosper and shine under my rulership.
As amusing as it’d be i doubt Tyrande would risk going after the neutral Goblins, in any kind of meaningful way. I doubt NE fans would be particularly enthused about a second tree getting bombed to hell and back 
Steamwheedle Cartel should join the Horde.
Under Erevien all that will remain of the horde is a bunch of smoldering craters where our cities used to stand because he has no concept of the lore or the world in general 
a.k.a Single player game 
So who is supposed to rule in the end ? You ? Sylvanas or Kael ?
You are not part of the Horde. You have already admitted that you would join the alliance if they offer you the chance. So don’t you dare talk like you care about it. I know you do not.
i never admitted anything of the thing but hey keep your delusion you have already by your many threads admitted that your not horde but a filthy traitor to everything the horde stands for you never ever was horde your a sylvanas simp and a Traitor to the sin’dorei if you was this openly a traitor in swtor the sith empire would be executing you for treason
