You are right and wrong at the same time. There is a basic skeleton and posture, in which all are stands. Concept art does not stand in any positions, it's just a drawing. So the basic posture and overall concept art, which begins working people "subordinates" was given from superior.
Now pay look at all models - they all stand in the same position
(- this all is compared with the old posture -): neck stretched forward, back hunch up, all broad chest and cobra shoulders, hands spread out a little (this from the front and in profile looks very unpleasant), bulging belly forward slightly. (In a topic about draenei we have quarreled on this things)
All of this can be seen in the drawings "you know who"...
----add----
They all had unique posture, and now the same. The difference remained only one (if not to find fault with some details), bf female head is omitted like it was on draenei f in tbc models and vice versa (that's why new be_f look like on their periods).
The same situation is going on with running animation - they are trying to make it universal but it was unique for every race.
Well, for someone it's good for someone don't, some people like some don't. But there is one simple fact which is difficult to argue: all this was different and those who "liked it/approach to their character's image" were left out in the cold. And for me it's humanly sorry for these people.
