I'm not sure if blizzard plans go further than just the cities were destroyed. They might give it a passing mention in the book that the night elves and forsaken live in camps somewhere.
If the Alliance do end up retaking Lordaeron, who would actually want to live there? Even if the Alliance completely demolished and removed every stone of the city and built something new, are people actually going to want to live in a place where thousands of living corpses dwelled for years, that is also haunted (at least I assume it is, since you can hear the voices in the old throne room)? I guess besides warlocks or DK's.
i think it is probably going to just be for dismantling purposes. like no one is going to live there, but no one can fortify it either. iirc lorderon was not resource rich either, low supplies of gold as per a quest in the starting zone trisifal. and yea you are right about the haunted thing too, they mention it in the undead starting cinematic.
it kind of sucks cuz its a heavy lore area
How about the f*ucked up side of Silvermoon?
WTF, you can literally store a rotting corpse anywhere. What're they gonna do about it, rot? Oh shit they're already doing that.
Forsaken might be harder to think of but I am sure that the Gilnean Kingdom would have a lot to repay when the Alliance takes it back.
FOMO: "Fear Of Missing Out", also commonly known as people with a mental issue of managing time and activities, many expecting others to fit into their schedule so they don't miss out on things to come. If FOMO becomes a problem for you, do seek help, it can be a very unhealthy lifestyle..
Well if they want to protect all of Kalimdor then the Horde needs to build big settlements in Silithus and somewhere North.
So my idea would be:
Orcs remain in Orgrimmar.
Taurens remain in Thunderbluff.
Ogres build a city ontop of Theramore.
These three cities will form the stronghold centre of the Horde civilization.
Forsaken can build up a Forsaken kingdom at winterspring and become a new scourge, with all those dead Night Elfs they can have a nice few years making new undead.
If Silvermoon would fall i would send the Blood Elfs to Silithus if the wound will become a new well of eternity, maybe they can make Silvermoon fly like Dalaran mages where able to do and fly it over.
This way the Alliance will have a hard time finding a landing zone to do dmg on Kalimdor.
Ofc this is all a maybe when the introduction will become true and that all of Kalimdor will become Horde and Eastern Kingdom Alliance controled.
Either dismantling purposes, so the Forsaken can no longer "bastardize" the land (From the Alliance's perspective) or a reclamation of the original seat of the Alliance's power, Lordaeron. Back in Cata, the Argent Crusade and Cenarion circle already had developed means of curing the plaguelands through druidic magic and consecration rituals, even if the land was Haunted, both parties involved could find another solution to put the souls to rest.

Omg how amazing would it be for all the diehard allaince lore nerds and Jaina obsessors to absolutely lose their shit if the Forsaken were to move into the ruins of Theramore and rebuild it in their own decidedly plague-ey fashion.
I play Alliance myself and i still want to see this happen.
One silver lining about the loss of the Undercity would be to see a new potential capitol city with the Forsaken's unique architecture (e.g. the newer version of Brill, New Agamand, Venomspite, etc.). Undercity itself is more a sampling of Scourge and Human architecture - I could see a new Forsaken capital with its dark gray and purple buildings, bristling with alchemical objects, Necromantic sigils, shadowy ritual circles, and enclosed by creeping fog and perpetual dusk.
"We're more of the love, blood, and rhetoric school. Well, we can do you blood and love without the rhetoric, and we can do you blood and rhetoric without the love, and we can do you all three concurrent or consecutive. But we can't give you love and rhetoric without the blood. Blood is compulsory. They're all blood, you see." ― Tom Stoppard, Rosencrantz and Guildenstern are Dead
Uninstanced Stratholme. Preferably reconstructed with post-Cataclysm forsaken architecture.
