I find it interesting that in the BG inforgraphic posted on the MMO main page a few weeks ago (http://www.mmo-champion.com/content/...Tweets-DLC-424), the win ratio of AV & IoC was hugely in Alliance favor. Something that seems to be a self fulfilling prophecy when so many Horde seem to black list it and refuse to do it, and you don't have to look far to hear some Horde get on their soap box about it.
Yet every single other BG had a much higher win ratio by the Horde. But those, of course, are perfectly balanced.
