A few readers sent us this post over at Border House that has laid bare (heh) the oft-mentioned differences in armor between the genders in World of Warcraft. While there are some exceptions, in most cases, the exact same set of armor (like this chestplate above) shows up as much more skimpy on female characters than it does on male characters. To the point of absurdity in some places -- even plate leggings, designed to serve as solid protection to the legs, appear to be more like plate thong underwear on the ladies.
As Border House points out, this isn't just WoW's problem. Fantasy and sci-fi in general have been the domain of boys in the past (even if that is changing quickly), and the sexual depictions in the genre have reflected that, for both traditional and financial reasons. As I pointed out the other day, all of Blizzard's luminaries thus far have been men -- is it any surprise that the game is designed from a mostly male perspective? And as BH also says, fortunately, WoW has lots of different gear. If you don't like what your character is wearing, then you can find something else.
