Make Kamadan in Istan the new LA. With it's central location between Tyria, Elona, and Cantha, ANet can use the LS to have us "retake" Istan. Then they can slowly roll out content into both Elona and Cantha.
If ArenaNet ever planned on releasing an effing expansion maybe they could develop Elona so that Gandara, the Moon Fortress is the last safe haven on Elona.
Thus would be the new L.A.
In 200 years time, I could see this fortress as a great city. The massive fortified walls are built against Palawa Joko's domain, a great advantage as a safe haven.
The territory of Poganh Passage could be the "Osgiliath" of Elona.
