I don’t think the forsaken can be considered as Lordaeronians since they have rejected their past, they don’t consider humans themselves anymore and they have destroyed many remains of the kingdom. The kingdom of Lordaeron is defunct.
The Alliance won the battle for Stromgarde warfront so maybe we can have them as an allied race. Alterac is also gone and now they’re the syndicate, plus they prefer the red team rather than us so i don’t think Blizz is going to add a human allied race to the Horde.
We definitely have to bring Dalaran back into the Alliance. Rescue the city from that neutrality bs and expel those brutes.
