I agree that it's a lazy that they thought of it in human terms.The bolded is the problem. They are not Human. Why would they have boobs? Also have you seen their mouths? did you imagine that on a nipple as well?
I hate the desing. Look at the lastest total war female LL
She doesn't have boob armour despite being a "skinnier"
IMO female predator is extremely lazy design
Their shape is very humaoid but I agree that some things like breast feeding must work kind of different with how their faces are designed.
It's just that her attire isn't really much different to what other predators we saw before were wearing.
Most of the time they just wear fishnets that expose their torso, with a few plates of armor maybe somewhere.
Actually she's wearing more than some, so I don't really get the boob armor complaint, giving her giant bulky armor would be weird, especially because they are more of the stalkery silent type.
They are alien, if it wasn't a design made by a human I could see her breasts being just as exposed as their male counterparts, cause they don't care about these things.
I just think that you are thinking of it humans terms just as much, just in a different way.
