I expected them to be roughly in the place of Kholusia narratively; to get given the big leadup, but to get screwed out of the actual finale. And it's plausible it might still get that (remember that half of Kholusia is 60/61), but it sounds like the whole thing is at the same level and roughly in the same place as Il Mheg or Rak'tika.
I absolutely expect a lot of the 6.x stuff to focus on Garlemald reconstruction, but as someone who's actually more interested in Thavnair than anywhere, that's not satisfying for me, either. ...especially since it looks like Thavnair is the FIRST zone, so it probably won't get much 6.0 spotlight either. Although at least Thavnair never begged for being Finale Material, just crafting material. ...that they might also not be getting, going by some of the rooms around Sharlayan.
