As small as it is, I'd really like to see the black-tipped ears separated from specific hairstyles and rather made a selectable option for Miqo'te. I think they're really cute, but don't care for most of the styles the feature is attached to.

As for butts, I'd be fine with a little texture stretching, I think? Something has to be done; I showed a friend who doesn't play XIV (I'll get him eventually!) some butt closeups the other day and even he thought the current state of our backsides is creepily unatural, and even makes some standing postures weird and impossible...
