As someone attempting to get into Pvp, this has been a huge turnoff for me.
I have noticed this too. MG Alliance seem to go after me or other WRA than others. Like we insulted their mother or something. Others me my guild that have been joining me have noticed it too.
The other deterrent has been gear. Trying to get gear while there are several that out gear me that seem to focus me for being lower geared them than them. It has sucked but been doing BGs to try to even the playing field.
Another is raids protecting the WQs. My bf and I just tried to head to one of the WQs and there was a huge Alliance raid just guarding it. I was unlucky enough to fall right in the middle of them. Trying to get out of there was like ringing the dinner bell. 40+ people fell on me in seconds. It was like that every time I rezed.
