Sylvari, Asura, and Charr are my favorite designs in MMOs these days. As much as I hate the Asura because of their society's personality (pompous jerks), I do enjoy their designs. I personally mostly play Charr, but that may be because of a combination of their cute yet dangerous designs, their race's backstory, and the Personal Story being the most interesting of the bunch (both Asura and Sylvari are also way up there). Sadly I only play it to raid on Mondays and Saturdays nowadays, but that's because I had a real bad guild breakup 6 years back where the guildmaster destroyed the guild while over half of us were on vacation...because of a bad night in WvW. It's hard to get back into the game for me after that.
