I absolutely agree with you. And I also thinks this highlights the problem I mentioned with this article: it lacks insight and perspective.
I'm confident, that Guild Wars 2, will not be able to maintain itself as interesting to the amount of people that are now playing. Once people become familiar and fun starts to become routine.
I've played to lvl 60 on my Guardian, and frankly, I'm not impressed. As you mentioned, it doesn't feel like a multiplayer experience. Even with lots of people around me, I'm often the ONLY PERSON SAYING ANYTHING. Why? Because communcation isn't needed. At all.
I have yet to fail more than one event, and that event was an escort I did ALONE. The game isn't hard at all. It's not a challenge what so ever. I'll just ress myself from downed, or get ressed on the battlefield or run back from the nearest Waypoint. I'm not saying WoW is any harder, but my gripe is that ArenaNet has not delivered what they talked about: Challenging, meaningful combat and "questing".
