On the guilds thing: Obviously, I can't speak for everyone. I do know, however, that Phineas' EG was and I think still is one of the bigger and more recognisable builds on Sanctum of Rall, and now on the megaservers that SoR players are likely to be fed into: if they're getting disillusioned and drifting into other games (or migrating en masse into Archeage: either way) this is a symptom of a problem. More personally, I have friends in Relics of Orr and occasionally join them to do various things - their leaders stopped scheduling guild missions because they found there were no longer enough members turning up to be worth it, and the average people online (representing or not) at any given time has dropped significantly since I joined. And I keep seeing and hearing similar problems in other guilds. I'm sure there are some guilds full of like-minded people that are all able to resist the growing ennui rather than dropping off one by one... but I'm pretty sure they're not representative of the majority.
Thing is, all this focus on the new-player experience really does feel like a bandaid approach to try to get more players and box sales. However, I'm not sure even that's going to work for them. People aren't likely to jump into a two-year old game, that hasn't had any serious expansions in that two years, without recommendations from current players... and I know I'd have reservations about recommending GW2 to anyone right now, however much I'd like to see the company succeed.
To stall the game's slow decline, ArenaNet really need to do something spectacular... but that's not something they seem to be willing to do. To draw an ironic analogy, ArenaNet now feels a lot like Adelbern after the Searing - too afraid of risking losing what he has left to take any action that might actually improve his position, and so by default his position steadily deteriorates until he's forced to pull the plug.
