I agree with you Theo about Gelmorra. Especially the Gelmorran Ruins in the North Shroud that have been enigmatic since 1.0.

And speaking of 1.0, I'd like to see some closure with the 1.0 Gridania storyline - what happened to Fye, Khrimm and their parents' 'secret mission' as well as the other Ala Mhigo veterans-turned-outcasts labelled 'wildlings' (Dunstan presumedly went onto better things in Gridania given he's had a anti-Ixal watchtower named after him post Calamity) - a theory was that they were actually part of secret mission to entrap the Garleans by using the elementals as a weapon, but nothing was ever proven one way or the other, so I would love to finally have some closure on this lingering plotline.

Also, how exactly did Yda and Papalymo entrap Dunstan, who supposedly kicked the butts of the Wood Wailers and God's Quiver sent after him? (Or was that, as was believed, the work of an Ascian?) Limsa and especially Ul'dah's 1.0 stories were given some closure in ARR and it's expansions but Gridania seems the one currently left out, so I would love to see these 1.0 things finally put to rest.
