Next 2 Allied Race Speculation

And none of them can be done?

Just because Blizzard had already decided to breed for the horde and vulpes did not need a huge overhaul, as they already use many attributes of goblins.
If Blizzard had chosen sethrak, they would have received all the service that was dedicated to the vulperas and other races, but were kept as NPCs.
Sethraks, they could receive the same treatment at some point.

Of course it would be nice. It just doesn’t work to tell the story of a people, just as it isn’t working for pandarens.
And it would certainly be stupid to have Shadowland beings slapping each other because they are in different factions, even though they both come from the same covenant.

Yes! And in that time, how many neutral races have we seen being added to the two factions?

They are like dragonflights and because they are something very disproportionate, it would not make sense for them to be a playable race, to return to Azeroth, to get involved again in something that was left behind.

Warcraft - Heaven Can Wait?

Nobody is there to spend the holidays and come back.
soon, we will see people asking Kaelthas to come back.

Mortal races are viable and none of these races in Shadowland are mortal races. Spiritual races.
