Just because it's beta, just because it's an opinion and just because it disagrees with yours does not mean it is useless. A thread does not need to be positive if it's offering subjective criticism over a change Blizzard is making. On top of that, Blizzard has released these models in the Artcraft series for THE EXPLICIT REASON OF WANTING FEEDBACK, which includes blatant criticism, constructive criticism, personal criticism, positive, negative and neutral feedback. I don't think I can make the above point any more clear. They want feedback. They want to know how they are doing and if they need to fix something that is not right.
In my opinion, the human female's do not sync up well with the old models (a white cutsey girl becoming a middle aged latina.) On top of that, the soft "sigh" they do in their idle animation on live turns into a dragon taunting cringing yawn in the animations and definitely needs to be fixed.
And before you start, yes, Blizzard can say they are a work in progress, but until they can release the -exact- work they are putting into the models down to "Adjusted left cornea on troll male eye to look straight" then subjective and constructive criticisms still stand.
Seriously, this whole crusade against opinions and criticizing Blizzard in general really shows who blindly throws money at corporations.
