Ouch. Definitely not the response I was looking for from ANet. I too had a friend quit the game (and get a refund) because he couldn’t play for more than 30 minutes without getting nauseous (which would last for hours).
GW2 is such a great game, and I’ve recommended it to many people (said friend included), but it’s a real shame that some people will not be allowed to enjoy the game because of an unreasonable stance on a very real issue.
