Everyone already gets the Main Scenario quest to visit all three cities, that could simply be the point that you're told that Ishgard is no longer safe for adventurers, or that the southern nations need aid. It wouldn't really affect much of anything, other than needing a zone or two dedicated to lower-level questing, before sending you back to the 2.0 content.
I'm pretty sure that the new zones will have low, mid and High level mobs, somethign ain to Central Shroud and the areas where the beast tribes are

The lone exceptions will probably the the Coerthas central highlands, ironically
