With the creating of side story content:

The 2 new adventurer's guilds

Will we see any potential for expansion off of a (to myself anyway) lost storyline which is the actual adventurer's guild?

I know that many seem to see it as also part of the storyline related to the Scions, to me however, it was the basis which we left helping out the city-states locally to aid the Alliance instead (the Scions storyline).
