I am 99% pleased with what we got with Miqo'te Face 4 in the Dawntrail release. The pupil shape on Sunseekers is a little too "cut out" looking compared to the original, and the nose lacks definition. I am exceedingly glad you added back the lip gap, a defining feature of that face. However, it seems some do not like it.
Au Ra face 2 was a drastic change to me and it affects an important lore character: Cirina. The new face is not a bad face, but it's not her.
That is the thing, very few of the changes for any of the characters can be said to be objectively bad, but I think it is very bad to force them upon people. Many are still noticeably different, and change drastically how people feel about their own and other characters. I think rather than going back and forth trying to please people the main focus at this point should be to add additional features to character creation/customization: More face options, more mouth shapes, more eye shapes.
I also think main characters like Thancred and Cirina should be closer to their original appearance as possible.
