First of all, "realism" as used in this context is typically shorthand for a combination of plausability, verisimilitude, a general grounding and consistency, and so forth. It's not an implication that everything must be exactly like reality -- just that those of us who prefer realism in games prefer that at least enough elements of the setting be presented in a realistic and plausibile manner to give the setting the general feel of believability. It even makes the fantastic seem more fantastic to have a more grounded background, in my opinion.
If the shorthand of using realism for this annoys you, feel free to mentally replace it with plausability, verisimilitude, believability, or credibility.
So this has pretty much boiled down to two types of people....
GROUP ONE: We want this completely optional armor asethetic in our game, but we do not at all want to force you to wear anything you don't want to.
GROUP TWO: I dont' like that, I think you are a pervert and things like that do not belong in my game! Their mere existence would ruin the game even if I never have to wear them, they exist. I am offended, sir!
So, really neither of the two groups is going to budge, this thread will continue and never be resolved until Dragon Age 4 comes out, at which point the thread will begin anew for it.
Hmm, to me it looks more like this:
GROUP ONE: I want female characters wearing sexy armour, because that's fun for me, so it's obviously actually fun for everyone. If you don't like it, you're against fun.
GROUP TWO: No, that's not fun for everyone. I'm cool with having that option, but let's leave the NPCs in practical armour, and make sure it's all equal between male and female characters, yeah?
So yeah...
I think this bias is rooted in the notion that completely serious people can't also be very sexual, sort of like Isabella and Aveline. You have one super serious incompetent type and one super outgoing tramp.
They can be. Nothing at all wrong with that. However, no, I don't think you'd find a completely serious person who is going to value looking sexy over surviving a battle.
I can't even tell any more whether you think that this discussion relates to all clothing and all aspects of the game or if you really don't see a difference between armour and clothing.
Everyone's trying to push their own subjective idea of whats "the dragon age theme and feel" without any proof to back up their claims.
They have said, in the past, many times. There were all sorts of quotes about how they were going for a "dark and gritty mature feel" and all that, not to mention various inspirations mentioned, and so forth. We're not just making this stuff up.
Screw genres and classifications, it's about universality now and everyone knows it. You can either claim it or fail at it and argue diversity of opinion is what prevented you from understanding what that happened to be at that moment.
It does appear to be trending that way, and personally, I find it a problem. I think that people are going to realise at some point that it's not the best way to go. Why? Because people
do have individual tastes and opinions, and eventually people are going to get tired of everything trying (and inevitably failing) to be all things to all people. I know I'm already tired of it.
What fun is there in making sense tbh? And what is decided as making sense or not? Women weren't considered to logically be fighting in a battlefield during most of human history. Not believing in god was thought to be complete nonsense, violent insanity even, throughout most of time. Should we enforce these things into dragon age? Maybe reverse them given the power of the andrastian church and its matriarchy structure and say only women are allowed on battlefields and men are bared from doing most everything else other then kitchen and farm duties. Who decides what actually does and doesn't make sense anyway? Whose subjective viewpoint are we using to set our objective bar of measurment here?
I find it more fun if things make sense because I enjoy a believable, coherent setting. I enjoy the idea that this is something that
could happen, assuming that the fantastical elements were present. I find it much more interesting if the characters in a world are reacting in a plausible fashion, and so forth.
Also, although it's true that it's always been rare, women have been fighting during most of human history. They weren't wearing chainmail bikinis.
I do agree that it's all subjective, but we can infer a fair amount of this from what we've already seen in Dragon Age and what BioWare has said about the setting, and so forth. Given that we see reasonably equal numbers of men and women fighting, there's no reason to assume that they wouldn't be wearing equally reasonable armour, for instance...
Considering crafting and customization is one of the big selling points for DAI, why not both? 
Exactly! Let people customise their armour to be however they want it.
And of course they find it "fun". I just think some people have really warped ideas of "fun". On the ME boards, alot of posters seriously wanted the Mako back because they thought it was "fun", even though it was about as "fun" to me as watching rocks erode. I also said something similar to players who wanted elevator loading screens from the original game back. I remember another thread in which I remarked in passing that I didn't think there was a single player who enjoyed the decontamination sequence on the Normandy in the original ME. But, lo and behold, several posters came out of the woodwork to declare that they did. All of those are textbook examples of "realism" destroying fun for me, and yet there were players who seriously believed that those were "fun". If their ideas of "fun" make me enjoy a game less, then yes, I do have a problem with it.
Hey, I liked the Mako! It drove like a Hellbender in Unreal Tournament and everything.
Come to think of it, the Unreal Tournament series is a great example of a case where I really don't care if things are realistic. Unreal Tournament 2004 is my favourite of the series, and it's probably the least realistic of the bunch -- but it's
Unreal Tournament, and the main purpose of the game is shooting your way to the top of the tournament. I don't care about the practicality of the armour, because contextually speaking, anyone fighting in the tournament knows they'll just respawn if they die anyhow.
That's all I am saying... choic is just that, a choice. People act like we want to remove their realistic armor entirely, and most (if not all) of us do not wish that. We just wish to be included too.
I think that most of us in this thread are, in fact, agreed that choice is best.
