I've had my say on the official forum when that's been up, seeing as it's taken down if the game itself isn't up.
Now the problem with that, is the fact that taking up the FoV issue there makes people who don't have a clue sadly, drown it out with a bunch of other camera issues, the most common reply to "include a FoV slider so I don't get sick" being "omg yes give us more zoooooomz"....
It's really devastating to go through the official forum because of this.
Secondly I've managed to be in every beta weekend and stress test and have posted tickets in game regarding this issue. On one side those won't be drowned with useless comments, but on the other side they don't get a reply either as far as I've seen.
Now other than bringing the issue up here, I've had my say on other sites including, but not limited to, arenajunkies, guildwars2guru and various other forums.
And because people so often fail to grasp the concept of FoV more often than I like it gets lost in a sea of people wanting to zoom out more...
And as far as official replies all I have seen is (ofc) replies on camera position and camera zoom, but not specifically regarding fov.
But I'll keep trying. Somebody has to...
