I don't think its so much that they don't want to give impression that you can play a female (or other race) character, but that they don't want to give the impression that it's a fixed character (which is what will happen if someone sees only that advert).They do spend a lot of money on this stuff, so they probably have more idea of what works and what does not,even if we don't agree with it.
I feel like they're backing off on giving an iconic face to the game, though, which is another reason why it seems strange that they aren't showing more diversity in the protags so far. They have made him so deliberately generic that you can barely tell what he looks like under that helmet--except that he's a human white male. That's why I find it odd that they aren't showing more than one kind of Inquisitor so far. It seemed like a deliberate tactic to make the person underneath the helmet interchangeable with other kinds of people, but so far that hasn't been the case.
But more to the point, I think women are awesome when they are feminine, or masculine but i definitely feel that there is beauty for men and women that appeals personally and externally. What men like out of a beautiful female character, is not necessarily how a beautiful woman wants herself presented. Many people point out how muscley men of muscles TEND to appeal more to male power fantasy than a woman's ideal of a man in regards to looks.
That said, feminine women take the helm, what do you think is beautiful, pretty, empowering, or sexy in a character you want to play, but less shown by modern characters made for men?
Ooh, that's a huge question. The thing is that I want to play all kinds of women. I want to play quiet farm girls who have never picked up a sword in their lives but learn to fight to protect their land. I want to play morally grey anti-heroines who are hard and stoic but caring, who struggle to make the right choices. I want buff militaristic women who can kill you seven ways in ten seconds. I want to play sheltered princesses who are forced to save themselves from dragons and decide they love swords as much as they love big ruffly dresses. I want ladies with tragic pasts (that DON'T include rape), ladies who kick butt just for the fun of it, ladies who never consider the idea that they can't do something just because they're a girl.
No matter how she looks, I don't want her objectified. That means the camera can't pan over her breasts or linger on her butt--hello, Miranda. Even if she's overtly sexy or flirty, she needs to have agency. The game needs to remember that she's the protagonist, not the object of the male player's sexual desires. Would she choose to dress herself in an unsupportive bra and impossible-to-run-in-heels? No? Then that's not enough agency. Many women do like dressing up in a way that makes them feel pretty or sexy--but rarely at the expense of safety and comfort. If a male character would get a badass trenchcoat and sneakers, then she'd better get the same.
I don't have one particular physical appearance that I wish to see, other than more variety. Women only ever get to fit into one particular body type, whereas men, while they are also idealized somewhat, at least get a wider range.
