Human Thief 295*
Human Guardian 223*
Human Mesmer 218*
Human Warrior 190
Human Ranger 172
Human Necromancer 157
Human Engineer 114
Total humans: 1721. Human most popular race in general. Humans invented guardian, so not surprised human most popular choice for guardian. Charr invented engineer, kind of surprised at how many human engineers.
My choices for human: guardian and engineer. I see guardian as like a paladin. My idea for human engineer was that he picked the profession to use charr's own tactics against them, then his queen ruined his plans by making a peace treaty with them. Guardian will be dignified. Engineer fierce, which I hope lets him hit charr NPCs.

Sylvari Engineer 44**
Total sylvari 1276. Voters seem to have stuck with the idea that the race closest to nature would prefer the professions closest to nature. I guessed correctly that engineer would be least used profession of sylvari. I think Killeen, the sylvari necromancer in
Ghosts of Ascalon helped make sylvari most popular choice for necromancer. Sylvari third most popular choice for elementalist, after human and asura.
My choices for sylvari: elementalist (first character I plan to play) and necromancer (leafless tree, winter skin look great for sylvari necro).
Asura Elementalist 290
Asura Thief 179
Asura Engineer 177
Asura Guardian 148
Asura Necromancer 129
Asura Mesmer 114
Asura Warrior 94
Asura Ranger 67**
Total asura 1198. Not surprised by popularity of elmentalist, am surprised necromancer and mesmer less popular than thief, engineer and guardian. Not surprised guardian, with its use of magic is more popular than warrior.
My choice for asura: going against the grain here, warrior. Wanted one ever since I saw concept art of asura in plate armor. I could have chosen guardian but I like the idea of a member of a highly magical race choosing not to use magic in combat. My idea is he prefers to beat sense into the "bookahs" rather than trying to talk down to their level

Charr Warrior 235*
Charr Engineer 203*
Charr Thief 94
Charr Ranger 91
Charr Guardian 79**
Charr Necromancer 69**
Charr Elementalist 50**
Charr Mesmer 20**
Total charr 841. Charr less popular than it would appear on other forums. Charr clearly Arenanet favorite. In lore charr distrust magic users, seems players going to take this idea seriously. Engineer developed by charr so makes sense popular choice for charr.
My choice for charr: thief, female because I like look of female charr better than male.
Norn Warrior 180
Norn Guardian 162
Norn Ranger 126
Norn Necromancer 70
Norn Elementalist 57
Norn Thief 51**
Norn Mesmer 46
Norn Engineer 45
Total norn: 737. My guess is norn least popular race because they're perceived as just big humans, though they have a very different culture. Humans (like charr) tend towards groups, norn very individualistic. I wasn't expecting guardian to beat out ranger.
My choices for norn: ranger and mesmer. I chose ranger so I could start of with snow leopard pet and looking forward to one day turning into a half-norn/half snow leopard. I choose mesmer because I liked the idea of a big strong norn preferring to use brains over brawn. A picture of a norn mesmer clinched it. Memser will follow Raven.
