Guild Wars 2 is great so far. I am hoping it is in the long term plan to add more armor options for all classes. My first character I made is an Elementalist, and so have put the most thought into what would help make Elementalists more unique within their profession.
Element based armors. I have seen a fire stylized set already in game, at least portions of the armor had fire like the helmet eyeholes. Add a “water” armor, which features ice shards, an Earth armor with a boulder type theme, and an “air” armor with an electric theme.
It would be a nice immersion addition.
