The Blindfrost is still a place we need to explore, and if 8.0 will have a tank, Viking from FFIII could be that tank. Of course, the south and Meracydia will eventually be here, but I'm actually more interested in seeing the North. The areas of frost and ice, in the areas surrounding Garlemald as an 8.0 expansion. We haven't had an "ice" expansion yet, and now would be a good time to do it, with talks about the 5th Calamity, which was the ice apocalypse.
