This might explain the lack of female torsos on the female figures.
Yup!
I got some more today, but ended up with a lot of duplicates.
In total I've bought 25 - 4 boxes (3 eggs in each) - they were £2.80 each, & 13 individual (£1.25 each, 90p with Nectar card) & I've got:
6 x Aquaman
5 x Black Adam
4 x Harley Quinn
3 x Batgirl
2 x Flash
2 x Supergirl
1 x Batman
1 x Catwoman
1 x Cyborg
Not sure if this is representitive of the ones that are more common, or if i was just unlucky ending up with so many Aquaman & Black Adams.

(didn't get Joker, Riddler, Robin, Mera, Wonder Woman, Superman & Green Lantern).
I feel like I had less variation from the boxes of 3. Out of the 12 in these I only got 7 characters - 4 Aquaman, 3 Black Adam, 2 Supergirl,, 1 Flash, 1 Harley, 1 Batgirl
With the individual figures (13) I got 8 characters - 3 x Harley, 2 Batgirl, 2 Black Adam, 2 Aquaman, 1 Flash, 1 Cyborg, 1 Batman, 1 Catwoman
I've ended buying another 5 on the secondary market (Joker - who I REALLY wanted & hoped to find in the ones I bought, Riddler, Robin, Mera & Wonder Woman), but once they arrive will still be missing Superman & Green Lantern.
I'll attach some quick photos I took the other day to show what they're like
