I dunno, the fact that Calia is on Azeroth and not stuck in a sword? The fact she still has relevance as a prominent leader and a diplomatic figure between Horde and Alliance? The fact she still has plenty of relevance to the future Light vs Void storylines?
I find your questions very odd sometimes. Like, we're not even talking about hints st this point, just basic plot relevancy, and you seem to have a hard time grasping what is actually relevant to the plot we have right now.
