Which is an improvement but doesn't negate the fact they were the go-to pure evil faction of the past 30 years.

Yep but the boobs came in the Rogue Trader era so its not like its a recent stuff up. The male torsos might be acceptable, but the heads are not. No one can seriously argue they could be mistaken for women.

Just look at how Star Wars did it:
Stated they recruit men and women as Stormtroopers
Mentioned a few unnamed Stormtroopers were women
Introduced a named female Stormtrooper in TFA
Has a couple of voiced female stormtroopers in TFA

No big effort or statement, but it had the effect of making the setting much more female friendly because now you don't know if you're looking at a male or female Stormtrooper when you look at one. It wouldn't be hard at all for GW to do that, easier in fact because they don't have to worry about voices or unmasked appearance. They just don't seem to even think about it.
