I would love to see Cantha in GW2. I want to see my beloved giant city all grown up in a Steam-Punky way. Just imagine riding floating steam-trains through the city. See Statues of Master Togo. The Lore was epic and the missions were challenging and yet satisfying in my demands for story-telling and eye-candy. Indeed Cantha was the first campaign I completed in GW1 because I just wanted to know how the story ends.
Don’t throw away one of your masterpieces NCSoft. Make it happen. Revive Cantha!
