It's also possible that the horns and hair were both allocated from the same bucket of zots. That is, time spent on the hair would've meant less time spent on the horns.
Those horns were given lot more love though
There was variation and good texture. When comparing qunari hairstyles to human one's for exaple, human one's have better and more variable styles and also the texture and overall quality is better.
I think the time forthe qunari hair should been taken anywhere else and put to that hair. Less horn options, less make-up, maybe take something away from other races since they have lot more stuff than qunari (more hairstyles and also tattoos, and helms!). I think the hair shouldnt be breaking point when chosing what race to play.
