Why would that be bad (assuming one has access to reliable data)? Is positive discrimination much better than the other kind?
Personally, I think many of us are losing track of the bottom line. DA:I is a video game that really is up to Bioware to make (unless something really heinous is portrayed therein) and it is up to us to buy it. Or not.
Having minority characters in the exact proportion that they are in real life comes with a number of challenges.
Which demographic do you choose to represent?
If its the whole world, then pretty much every character should be a chinese male, which would lead to a similar issue that we have now of an over saturation of similar PCs ( these days its the, white brown haired male with stubble)
If it's gamer demographics then, which gamer player base do you look at representing? your own game, similar games, gamers in general?
Plus all this leads to a negative feedback loop, game developers don't include certain characters because they're in in the right demographic, so those people are less likely to play games so game developers don't include those characters.
Positive discrimination can serve some good by exposing people to views, people, experiences etc that are not their own. Thus lessening the negative effects of ignorant discrimination because there is less ignorance.
Personally I would like writers to be able to create characters that they think work well without having to look at demographics and think about being inclusive, however people have a lot of inherent bias that they may not be aware of that would prevent them from naturally creating a diverse cast of characters.
Writers grow up in the same world we do, full of the same tired out tropes, so it's only natural for them to fall into doing the same thing.
Until our society and culture could be considered as equal, then writers must decide to create diverse casts of characters, to challenge outdated beliefs and ultimately help us all work towards are more equal society
