OK I’ll give it a go. 
Since the beginning of time, well at least since the invention of the video game, there has always been the gap between the needs of code and content, left versus right thinking, where code is all about ones and zeros smashing into each other where content, player animation creation, is a visual process of being able to see the process change over time as to iteration and inspired creation.
That’s to say that code has to work today based on a purpose that is general by nature where content can take days or even months based on the perspective of the artists who see the would based on some form of reference as to the result they are looking for. It’s the only option unless you can see into my which is a scary place to be.
In the case of animation the devil is in the detail of function following form so using a male form to create female animations the result usually lands up with your female character looking more like a drag queen rather than a female by design. It’s just human nature to work with what you see and female movement on a male figure just looks goofy. It simply does not or will it ever look right unless of course your character is a drag queen.
To me it’s not a problem, I’m a big boy and can afford the toys I need, but lets not forget the 12-14 year old who can not afford to buy food yet alone off the shelf art assets.
A bit of a rant, from an artist perspective, but hay if it does not “matter” than the end result will be the mess that is Mass Effect.
