Just a thought.
Guru has a decent size user base, but is small enough that you can recognize the regulars if you frequent the forums enough. Unfortunately, there's a number of those regulars who have made it their daily 'habit' or 'ritual' to come make a slew of negative posts on what ever they can find. Some of these users, by the sounds of it, actually play GW2 regularly and I think just do it out of habit at this point (discussion is discussion after all, what ever gets ya going).
This has been going on for months upon months, it's not a new phenomena and has been discussed and brought up a number of times. The op is just the next person to get fed up and leave, as the guru community slowly bleeds out.
