I wouldn’t hold my breath on that note.
I 100% think Calia said something as non commital as she did because they aren’t going to touch Gilneas.
Because I am genuinely starting to believe there’s something screwy with the code there. We know they dont touch Quel’Thalas because it’s tied up in Outland. As Gilneas was designed to be a EBG and is so phased locked it’s notoriously difficult to use it as a sandbox I think there’s mechanically something wrong with it.
Seriously I tried staging a fight with some Alliance outside SFK and we kept vanishing into parallel universes anytime someone got too close to Greymane’s Wall.
