"Margrave Sin'dane has asked for our assistance in dealing with allies of Kel'thuzad. Make them pay!"
What?
Kel'thuzad is here?
Margrave Sin'dane is friendly now?
This worldquest feels like spoilers for something that hasn't happened yet, atleast not to me as Night Fae. Either I should've been notified in some way that Margrave Sin'dane is on our side (or whatever is going on there), or the WQ voiceline should've been different per covenant, similarly to how Broken Shore gave custom voicelines per class.
This might've been intended and something messed up though, as the description says "Sin'dane's Forces disrupted" with no mention of Kel'thuzad.
