Chill, this is just the usual forum noise. All game forums are like it, its just a few noisy bored people who get more entertainment out of trolling than playing any game.
You mentioned wow and in the biggest forum **** fight over there (realID) there were only a couple of thousand unique posters out of hundreds of thousands of english speaking customers who posted so don't expect this forum to come close to mirroring the game population.
The first month will clear out the people who didn't know what the game was about anyway so thank them for not doing any research and paying BW $50 for something they never were going to like and wave them on their way.
