Want to know how diverse Blizzard actually is with female characters in their games? Look no further than World of Warcaft and two of the most important female characters, Jaina Proudmoore and Lady Sylvannas Windrunner.
Jaina is dressed conservative (though with an exposed midriff), which might be normal considering her class (a high mage). More attention is given, though, to what she goes through, especially lately seeing Garrosh lay waste to her home town of Theramore and her becoming blinded by revenge, forgetting of her desire for peace (she once had an intimate relationship with Thrall, former leader of the Horde before he joined up with the Earthen Ring after the Shattering). I haven't played WoW after 5.3, so I don't know of how her story is currently, but she is seen as strong willed (and seriously, you didn't want to mess with her if you were going to raid on Theramore on a PvP server prior to Mists: she's not fucking around).
With Sylvannas, though, she's a lot more sexualized that Jaina is, as you can see, but many think she's allowed to because she's a complete and total badass. Hunter class and has an entire history with being Undead and serving as a Scourge under the Lich King. She can also be very manipulative, and not even the Horde really trust her (Garrosh hates her, though by the end of Mists, he becomes very exposed for the sack of crap he is).
Simply put, I think Blizzard is one of those companies that doesn't think that sexualized dress code doesn't mean the woman who's in the threads is any less of a person. Maybe the RPS interviewer should've looked at all the women they've made in WoW to know that Bowden is completely correct in how they design characters. It's all within their context (you wouldn't expect the hunter class in WoW to wear plate armor, would you?).
