The current content is greatly scoped down, and another thing to keep in mind is the nature of something like GW. I'd guess the game as it will ship on CD is done (takes time to get out to printers ect ect after RTM and then all boxed up and shipped to stores). However, the content is always changing. Just last month, the character creation was different then it was last week. I've seen screenshots of how it USED to look, and it's completely different than that, too. With a project where developers can constantly make changes and update a game daily, you never know what you're going to get. Candy canes? Pumpkin heads? That stuff cropped up overnight! Just think of all the other stuff that could get added, even this *weekend* for all we know.
Not saying that complaining is bad, of course; constructive feedback would probably be useful to Anet anyway, and there's *nothing* wrong with having an opinion!
The point is that it's an evolving beast, and what you see isn't always what you get in this case.
