The only thing is that Blizzard didn't do that. They made them look like badass, midevil characters. Even if you don't know a reason why a woman would want to expose a midriff, there's another point: why should any woman HAVE to give their reasons. Want a reason? She felt like it! Or maybe it was a trendy thing in that world or that setting or whatever for women to desire those types of outfits.
It's not as if Blizzard made any of the ladies in their games to have weak, submissive personalities that are not out of the characters they were designed to have (there are weak, submissive personalities in both genders). You know by watching what they do that they are strong and independent, so why should we doubt that they would wear those clothes as a sign of independence? Are we being just as sexist to tell them to cover up? If Blizz did also make these women weak out of their context while donning those threads, then I might see the point, but they are not. I don't think it detracts from the characters, but rather adds to the particular mid-evil like setting that Blizz likes to place the games in and adds that sense of coolness that they said they wanted in the games. It gives the sense of "hey, this is what I want to wear, and I dare you to tell me to put more clothes on".
Plus, regardless of what you may think of the morality, I'm not sure where in any of this we've lost that RPS did a disservice here. We get that they ambushed Blizzard here. There's no denying that because we know what an ambush is (a person trying to get an unscheduled interview by just running up to you and conducting one without even asking if they have any time or not, regardless of where they could be). Hell, those are very disrespectful to begin with because what if the person was with their families. But then the interviewer goes in there, wording the questions as if he's already got the agenda, and three times asked the exact same question a different way, and all the times, Bowden gave the same answer. And they called it "avoiding" them when he finally had enough of the bullying. It's yellow journalism at it's finest, and RPS has no shame in doing it if you read their editorial that only doubles down on the point that they already had disproven.
And why did they do this? They do know they would get hits, but WHY did they know that they WOULD? It's because it's the "thing" right now to complain about misogyny in games. Not to say that it doesn't exist or that nothing should be done when it pops up in games (to avoid getting the logic-breaking label "concern troll" thrown at me), but someone brought up the Tropes vs. Women series before me in this thread (thank you to whoever did that so I don't get accused of interjecting that into this, by the way), but I've noticed that a lot more people suddenly care about this because of that series. You might think that would be a good thing, but from what I've seen, and it's evidenced by this RPS crap, that those bandwagon hoppers don't really care about that issue, and just see it as because the series is popular, that they can coat tail the issue to score a mass amount of hit pieces by claiming misogyny where it doesn't actually exist, because we know enough people will bite on it without even doing their own research. It's like the people that blindly supported the War in Iraq on the basis that it had "something to do with 9/11" when Saddam hated al Quedia as much as we did!
If you really are motivated on those basis to do something or to question morals, then by all means. I don't question those people. But when you contradict yourself and you do what RPS clearly did, then you should be questioned as to what you're true motive is, because it sure as hell isn't to install a better representation of females in games.
