It's less of a danger than going into battle literally topless. If they wanted to make that joke, fine. But having the person with the least practical armor in the history of Dragon Age say it is stupid.
He doesn't always have Vitaar painted on him. His canon armor doesn't have it. So he has no defense whatsoever. If that's acceptable to the Bioware team, it should be an option for the player. And compared to what he wears, the boobplate armors are very practical.
Also, in truth no armor in Dragon Age is realistic. If the armor was realistic, the person wearing it should be killed the first time they are hit by magic since: if hit by fire, the armor would cook them alive; if hit by cold, the armor should freeze onto them and give them lethal frostbite; and if hit by lightning, they should literally explode by their armor serving as a lightning rod and directing the full current straight into them. Now you could argue enchantments to counter that, but if enchantments can counter that they can counter the weaknesses of the boobplate armor.
Good point.regular armor wouldn't work in a world in which lighting,flames and ice can be used in battle.Thus it would be good for developers and authors to not ignore this.
Another important part of having the laws of physics and logic governing a fantasy world is that authors will need to be more creative in navigating through constraints.Rules can actually increase impetus to be creative.
For example an author can:
Imagine types of armor with exotic materials that help against elements like lighting and freezing.
Take the game of thrones route,where magic is extremely rare.Dragon age takes this route to an extent,mages get locked up,so a soldier is more likely to be stabbed to death rather than burned or electrocuted.
Create a world where every competent fighter must learn some basic defensive "magic"(templars,witchers).
