So, I'm not entirely sure of this since this is one of the plot points in BfA that won't get much exploration until the future...
Though a lot of people seem to forget about this event that happened in Dazar'alor. We were pre-occupied with Azshara and N'zoth that we overlooked the moment in Battle for Dazar'alor where the Alliance has killed King Rastakhan as one of the major boss fights of that raid.
Wouldn't Talanji have some sort of vengeance against the Alliance for killing her father?
Is that a possible plot point they might explore or just no?
