I can’t ignore this anymore! Something should be done about it!

I actually think the butt on the mithra looks smaller even if it sticks out farther than the back. It's about how the character stands, not necessarily how far their behind sticks out. The difference is, the mithra has less of an arc (curve) of the back. In fact, the mithra looks more 'manly' than the miqo'te, by far.

Uncommon (but not unrealistic) hip ratio aside, I really think the small behind is fine. I mean, people who are that size do exist. I'm one of them. Would you like me to upload a picture of my behind so you can analyze it and draw lines? :P

Edit: the real difference between 1.0 and 2.0 is something we've known about for a long time -- sliders for the breasts. You can have your huge breasts if you want. However, the huge breasts make the butt look small. Ideally, we'd have sliders for both, but I really don't think the miqo'te look 'unnatural'. The reason the armor sticks out like that is to accommodate the tail, which needs to move and swing around. I know because I've cosplayed a mithra/miqo'te and yes, that tail needs room.
