Guild Wars 2

As the Mists become more and more important to lore over time, and fractals now taking on some of the main story (starting with Thaumanova), I would eventually like to see the inclusion of a Mists-themed guild hall.

Not only would this be an ideal guild hall for non-PvE guilds (as PvP and WvW take place entirely in the mists) but it would also be a good choice for PvE guilds that specialise in dungeons, fractals and raids.
