I love the Sylvari because there is quite a lot of mystery around their beginning and because they are so connected to nature
I have one human character, but I have four Sylvari, and my main is a Sylvari.
The customisation is awesome on Sylvari characters too because of the different colours of skin, pattern and glow. Recently my room mates and I made four Sylvari elementalists and we each use one of the elements and we customised our Sylvaris to look like their respective elements. They look really cool running around together xD
I have characters of every race, though, and it’s always good to mix it up and try new things ^.^
