I think it has to do with some players; honestly the attitude one encounters sometimes....... it's really sad.
These just create a bad image of wow-players in general.
I read sometimes things as:
OMG maintenance will take 2 hours longer... what am I going to do? I mean, seriously....
It seems that without wow, some people can't even fill 1 minute of their lives.
I don't know, but just reading some comments or remarks make me think that these players (how few or many there are) have nothing else to do in their lives.
So the perception from people who don't play games or don't play mmo's or wow could be a bit different that they would think.
