Flying in 2.0

[Atoli]

Not with 2.0, but later as an expansion would be nice
Obviously it shouldn't be just the flying feature but dungeons and islands in the sky, maybe even with parts you can and some parts you can't stand on and in dungeons, you'd have to stop flying sometimes and fall through the "ground"(clouds?) to get deeper into the dungeon or find secret pathways..stuff like that

I'm not a fan of useless flying feature though.

The only thing I remember like this was only one Aetheryte Crystal. It wasn't a floating island.

It's neither an island nor an aetheryte, the artwork was of a flying Garlean base.
Well, we already know their flying technology is pretty advanced
