What you are quoting is a general news post on the main page of the support site. That page is the Support Site, and it has the “Submit a request” near the top center of that page. The form that is presented when you click that link is your webform.
This is not a circular link, although you may assume so if you only read the news post.
I will ask our web team if it’s possible to make the Submit a request section a bit more prominent, but I don’t think they’re modifying the Guild Wars website, so I think folks will just need to look around on that page to find it. It’s definitely there.
