New Jobs Gated Behind Completion of 2.0 Story?

[Felis]

How were legacy characters introduced? That's something I missed out on.

No carriage for our 1.0 hero, we had to walk.

It is a commonly accepted guess, but just a guess. Basically, since there are no zones that could bring to new areas (or does SE intend to just slice off mountains in Coerthas Central Highlands?) the assumption everyone makes is that once in Ishgard, you will get your flying mount, and with it access the other areas otherwise unreachable. "zoning" probably will not work with flying (unless they plan to patch the sky with those blue trails?), so we're assuming that Heavensturn will be more of one large open world, similar to 1.0, with areas on several levels and accessible through flying.

I guess that the Ishgardians find a way to the other side of the Snowcloak glacier to Western Highlands after the 2.55 story. Then there will be a NPC or a portal that bring you to the other side (like the NPC at the White Wolf gate in Gridania).
After all, since the event with Shiva they know that the glacier is full with tunnels.
