Well they didn’t really need to find a place to put them, the allied race castle is where they all go.
I very much doubt this was the reason, its just one faction name and a reputation bar. They don’t even need new leaders, the leaders are neutral and the individual player character decides to go whichever way. Its just old mentality of the developers to keep building on top of foundations that are old and obsolete.
It makes sense the nightbourne would have totally been on board for teldrasil burning as they hate the NE. All of this was told in legion.
This is hilarious considering this guy:

Its like basically everytime Alliance affiliated character do something for a Horde race they get this reaction from them.
Nightborne shouldn’t have been on either faction, but then I dislike the concept of Allied Races in general and have suspected for years they were a last minute expansion hook for BfA, cannibalizing assets for the customization overhaul to do so.
The Suramar arc is one of the best things Blizzard has ever written, and holds up to this day. Having the Shal’dorei join any faction, let alone the Horde which immediately plunges them into a war, cheapens that ending and entirely undermines Thalyssra as a character.
So one guy vs the leader of the NB outright speaking if the hatred of the nightelves for abandoning them and being a reminder of what they used to be. Some sound logic you got 
That one guy ensured the survival of their race and the success of the rebellion.
Just like Velen purifying the Sunwell… you really exhude the “what have they ever done for us” attitude but unironically.
The “blood elves” really care about the nightborne thats why they join them.
Oh the magic tree that gives us magic fruits for us to survive?
Dont worry about it. Its nothing of consequence. What have the Night Elves ever done for us???
This is why the faction divide for certain races is just dumb.
Haven’t done the questline in forever, but what have the NE done for the Nightborne, outside of Tyrande admittting they plan on using the NB as cannon fodder so the Kaldorei don’t risk too many of their own people?
You work with a Night Elf druid to restore the acandor and feed the Nightborne as they and you + allies try to take back suramar.
Without the acandor Thalyssra would have never succeeded. Probably wouldn’t have survived long without the trees fruits.
That was one Druid who made the decision on his own to help.
Again, what has the kaldorei society done for the NB that warrants their loyalty to them?
Please quote me where I said this
You constantly join mid discussion made assertions no one made and get mad about it. Its just so tiring. Can you put me on ignore so I don’t have to put up with this?
Fact is 1 Night Elf made the survival and liberation of Suramar possible. This would go against any idea that the NB hate the Night Elves.
Okay…but 1) Nobody’s mad but you and 2) I asked why the NB owe the kaldorei anything and you’re throwing a fit over it
If you can’t answer it, that’s fine.
You do this every time someone presses you for an answer to claims you make.
Its just words and logic have no sway over you.
You keep moving the goal post and if you don’t get it your way you freak out. I prefer to skip the hours and hours of drama to skip to the end where you proclaim to put me on ignore.
Fact is the NB relationship with Night Elves is complicated and grey. So it would be logical for some to join either faction that they identified most with. 
Much more logical then joining a war of extermination to kill every Night Elf they could because they despise them or something.
Nobody but you freaking out buddy. I asked why the Nightborne should join the Kaldorei and you threw a fit when you couldn’t answer it
Sure thing.
Thats what happened. Can you do me the favor and put me on ignore? Please and thank you.
I mean fine. Since you can’t answer a simple question and you threw a fit over it
Excellent.
God bless. 
Since Smallioz can’t answer a basic question without throwing a tantrum. Anyone care to explain why the Nightborne owe the Kaldorei anything or should’ve joined them after the kaldorei treated them like garbage and planned on using them as cannon fodder?
I mean, I didn’t realize it was a complex question after all
One Kaldorei helping does not mean much. That one Kaldorei has no known association with those in Kalimdor or their membership in the Alliance.
Farodin, like most people in Legion, were representing neutral orders or organizations, not the factions.
That’s what I said when I said it was just one druid, but than he lost his mind on me when I pressed him for an answer about why the Nightborne owe the Kaldorei anything
I’m gonna disagree with the principle. The Horde needed a Night Elf analogue since the possibility for Horde Night Elves is non-existent now. However I think the method they used to drive the Shaldorei into the Horde was asinine and uninspired, it’s basically Blood Elves 2.0.
It just highlights how creatively bankrupt Blizzard is now.
