That's the issue people have.It's 2024 and progressives are demanding it, so make your guess...
If GW wanted to make an extra buck or few millions they could start trying to compete with Japan for the spicier part of the market with the assassins, the dark eldar, various gangers and so on, if they wanted to be a bit more tasteful they could also bring up more noblewomen with 40k's gothic inspired style (being nobles they have the excuse of being inherently important enough to bring up, and it would serve as good cosplayer bait speaking of women who may be interested in 40k), but we both know they would prefer not to do that, this is about virtue signalling to a particular segment of the audience who even if it's interested in "female representation" is not so much interested in the kind of females the typical man would find attractive, and who care more about their out of 40k politics being represented in the lore than about 40k lore.
Why not focus on the other factions?
Like, the SoB...
But we will see what comes of this
