I would personally enjoy going back to the Eye of the North expansion concept. Where we got to travel between asura, norn, and charr areas and help the factions with their own problems. Whether these need to be expansions of their own, or Living world, would depend on if they plan to incorporate multiple storylines into one for a greater purpose. Either way, the idea of traveling north from our current map is intriguing both for nostalgia, and for new players who didnt get a chance to experience the Charr and Norn lore as much as us veterans did. But regardless, Cantha does open up a huge new storyline, whether it is human or not, it will definitely change the scenery and enemies, as well as hopefully a new race (tengu). So I will vote yes for Cantha, even though it is more of my second choice.
