First of all, I wanted to praise the people in charge of the maps and environmental art. It's phenomenal, and this is partly why I cherish the series so much.
I'm interested to know why Kryta went from a fully tropical climate in GW to a mix between tropical (mostly Lion's Arch and southern Kryta) and temperate (northern Kryta) in GW2. What motivated this change?
I must say that I feel a bit nostalgic about the beautiful white-sand beaches and the crystal-clear blue saltwater.
