Okay, I'm going to put on my devil's advocate hat here.
Vivenne: A mage that can specialize in barriers as well as the entire KE tree. Also, most of her armor covers up her cleavage as well.
Sera: Wears leather mixed with chain. Leather is oftentimes more form fitting, and she's not a front line fighter meant to be taking heavy hits.
Varric: Two things. First, not all of his armor sets has his chest exposed. Second, he takes a hit like someone would with their chest exposed. Even in good gear when he takes a hit it's a fair chunk of damage. I get stealth going for him to help with this. He's also not meant to be a frontline fighter either.
Solas: A mage with access to barriers.
Dorian: A mage with access to barriers.
Finally when it comes to Iron Bull, I don't find him the slightest hypocritical at all. For one, he is wearing a type of armor, the magical paint known as Vitaar. So it's not like he's strolling into battle unarmored. Both the Avvar and the Quanri have real world analogues with their fighting style with the Celtics. Think about wode which Celtic warriors used, now give it some magical properties because this is Thedas and that's how the writers roll.
I never ever saw him saying anything about, "That's how all women should go into battle." I'm betting that he wouldn't make the same remark about a female Quanri with a harness style outfit or an Avvar with her more topless look. Why? Because they aren't strapping plate mail to their chest and fighting that way. The extra plate armor can be as much of a hindrance as a help if designed poorly. In fact, it might be better to strap on some Vitaar and wear much lighter armor versus badly designed chest armor that a style like the Mordhau could completely take advantage of.
My entire takeaway from that was if you were a woman and going to be wearing plate mail, go practical. I saw the "ornamental crap" comment was more a shot at highborn ladies that put on armor just for show. I can completely see that happening, especially in a country like Orlais. Most of his experience with the southern lands has been in Orlais, and I think he's making his crack based on that experience. I'm betting he saw the most ridiculous armor while he was there for both genders. I was disappointed he didn't make a cod piece reference though. To keep things a little more balanced.
You know, Natashina, this is why I like discussing things with you. Even if I disagree with you, you always phrase your answers with eloquence and fairness.
That being said, I wasn't talking about the optional armors you can place your companions in that's "practical". I am talking about the default and some of the optional armor you can have them to wear that isn't considered "safe".
Going further in: Mages cannot maintain barrier 24/7, at some point, they're going to be completely drained if they don't maintain a balance. Of course, if you do everything by the reality set within the game universe and you role your mage as support only, i.e. barrier, then sure, maybe. If they're batting off barriers and combat spells, it's going to make them weak pretty quickly. Also, in Thedas, mages have a reputation as dangerous and feared, they would be the first thing taken out in a battle situation. Vivienne's default armor, as well as Solas and Dorian--are basically cloth. No protection against projectiles from the archer who is waiting for that barrier to drop so they can be eliminated from the fight. All three mages have vital weaknesses that can lead them to instant death, even from enemy mages.
Sera and Varric and even Cole start off with armor that is basically cloth, as well. Some of their optional armor is no better. Again, they can't maintain stealth and swiftness forever. As soon as they loose an arrow, they are known and any rogue or mage adversary is going to know when and where to strike, either with an arrow to the throat (as our darling Sera would demonstrate) or a dagger to the back.
Now, it being said that mages have access to barrier--- mages make great support roles because they can give barrier to their comrades and in-game, maintain it just as well for a warrior as for themselves. Warriors have access to Guard. It works like a barrier in that it has to be depleted before the warrior begins to take any damage to himself or armor. If warrior utilized their guard for up-close encounters, which they do because that is how it works best, especially with On Hit advantages, a skilled warrior would have ample time to deflect most frontal blow. At least, he/she would be able to deflect and prevent any killing blow just as well as a mage with barrier, who would be rushed by a rogue or warrior. Death can come to any, even the best outfitted.
If you look at the armor that was originally in question before people started bringing up chainmail bikinis and such, which was in Origins, it has just as much believability as a lot of the armors in Inquisition. This armor would be optional, just as any of the impractical armor used by any rogue or mage in Inquisition. I don't see people demanding that Vivienne or Sera's impractical armor be removed for it's "silliness". All most ask for is that there is a better option, a more practical option-which there are. Vivienne, Sera, Varric, all of them have better armor to equip. As would warriors if the Origin armor would be added.
I don't think I read one reply where someone was saying that this armor should be required or default. Only that it would be a nice option.
