Hazard a guess: new... map?
There is pretty much non-stop discussion on this in both the living story sub forums if you want to read up on the current speculations.
Opening up Maguuma is largely what is hoped
Regarding point 4 the only dragon that’s actually been in the game so far is Zhaitan.
And I wouldn’t say Jormag has its own themed area. The Northern Shiverpeaks were a cold, snowy area in GW1 before the dragon ever awoke. It’s more to do with geography that in-game lore. They’re close to the north pole and at a high altitude, therefore cold and snowy.
Kralkatorrik doesn’t have a themed area either, unless you count the Brand, but that’s just a strip it happened to corrupt.
Having said that the cut scene that introduced Mordremoth did indicate that its in the jungle somewhere (the line when from LA across Kryta and towards Rata Sum) so that probably is where we’ll be going.
“Life’s a journey, not a destination.”
On mag there even looks like an round places where something may be exploiting out of.
Guild : OBEY (The Legacy) I call it Obay , TLC (WvW) , UNIV (other)
Server : FA
I really want crystal desert. Like, really.
The new map is practically confirmed to be magus falls or magumaan wastes.
The round area Jski.6180 refers to is Dry Top from GW1.
