Oh...And I guess I'd better answer the post.
Sylvari are my favorite by far. If you read their lore, they're probably the most unique, detailed, and plausible (plausible for magical plant people created by a sentient tree, anyway) race I've ever seen in an MMO.
When I was younger, people would always talk about how badass it would be to be a bear or a tiger or whatever, but I've always wanted to be a tree more than any kind of animal. I know it's weird, but it sounds very appealing to me. And on top of that, sylvari are agnostics, panromantic demisexuals, and passionate about exploration and learning, which are all traits that I share with them. (And I'm 25 years old, which is the same age as the oldest sylvari, but that's just a coincidence.)
Plus: they have a knightly, chivalric society without gender roles (because why would they need them?), they feel it's their destiny to destroy the dragons, and they're vaguely creepy-looking. I love that. They could have so easily made them sugary sweet, but I really think they got this race down perfect. And it all makes so much sense with the lore! Normally attempts at making a race have complete gender equality and all that seem really forced, but in this case it's just logical.
And I love the fact that sylvari males tend to be more slim and pretty than average humanoid males in MMOs. I'm just so sick and tired of seeing hulking, brooding gorilla-like male characters everywhere I look. I know it's made a lot of people hate the males, but those people are awful and should be kicked. (No really. Expectations of hypermasculinity in males need to be smashed.)
