I believe this is a red herring. It would imply the Gridanian and Ul'dahn Starshowers are also related to ascians, but we have zero evidence this is the case. In fact, we haven't even found an ascian in those story arcs to begin with. The closest we have is a "shadow" attacking Farrimond's unit of Wood Wailers.

Circumstantial evidence yes, but it fits nicely with my perspective.
Of course he hits you! You were there when everything fell to pieces on him out at the God's Grip. This doesn't need to have anything to do with the Astalicia.
