Early Heavensward areas on Behemoth were...empty?!

[Slick]

I imagine its the same way on all servers. Don't expect any HW areas except for the Churning Mists or Hinterlands and on occasion, the Sea of Clouds, to be particularly active. Unless there's a hunt up and everyone flocks to the area like a pack of vultures.

Perhaps I am being redundant, but why is that?
