But... the realism argument really, really doesn't apply here. At all. If you have male characters in full, covering armour then it stands to reason that women - as defined by the laws of that game - would require the same protection, especially as melée and ranged combat are part of the game. People are shooting at you, people are running at you with close-combat weaponry.
What you're arguing, Kein, is that it's pointless to discuss because it's a game. Fine, I'll concede it's not reality, and that's hard going considering there's walking skeletons. But it is a taste and a balance issue. The attitudes towards men and women are not balanced if the men are in practical outfits (including armour) and the women are wearing sexualised or more revealing costumes. The female armour in Divinity 2 (as an example) was not as protective as the male armour. It left critical points exposed or carried a danger of its own.
You also imply it doesn't matter to you. Well... so what? Why bother arguing if it doesn't bother you? It bothers me, it bothers a whole group of people even, and it's not something that's going away at any real speed because developers/designers don't realise that it's even a problem. I like to give Larian some leeway with it because they're typically mocking fantasy games as a whole, but I still wish they would stop with it.
It's not just an issue with Divinity though, it's an issue with *gaming*. It's an opportunity for Larian to rise above the rank-and-file and do things right, and it can still do that whilst mocking other fantasy games/the genre itself.
