I'm hoping they might think to retroactively give him something to do, after all they've done with the Firmament effectively adding a new chapter to Heavensward.

People might recall I had a tendency to fret about how Francel had been left cooped up at Skyfire Locks with nothing to do all this time and no story involvement since ARR. The Firmament story rewrites that. They're Lv60 quests unlocked immediately following Dragonsong, and suddenly Francel has shifted from doing nothing to being very busy indeed. He wasn't at the Locks all this time - that was just a time anomaly until we did the quest to move him forward.

So, hypothetically they could do the same with Unukalhai if they wanted - slip in some kind of Lv60/70 quest filling in what he's actually doing at that point. Perhaps finally make the Warring Triad quests mandatory now that they've broken that MSQ-sidequest separation rule with CT.
