That sums up my experience. The community was never perfect, but the frequency of negative experiences I've had has been steadily increasing since June, especially on Crystal which had the most preferred worlds/new player destination. A lot of it in my experience has come from overly defensive players lashing out (e.g. a healer struggling to keep a tank alive, instead of asking for help, insulted the tank then rage quit). The negative effect is I got so sick of bad players being snippy, it's made me more grumpy (and maybe elitist seeming) to the point I had to stop playing with PUGs.
