I play 4 characters at lvl 90, only one is human. I thought that is unfair, wanted to pay for a race change for my lock, but then I realized that is no advantage to do that. I like my escape artist.
Idea is: if you compare the human racial against no racial (as op does -> human has 3% more pvp power) than looks unfair. But is not only 3% more pvp power. is 3% pvp power against whatever racial you have.
