V4 Morphs ++ was released along with V4 Base and gave you the possibility to create many different body/face combinations  - this is what Dawn lacked upon release.   If you look at early renders of V4 you can see how people were excited at the prospect of "unlocking" so many characters instead of having to pay for a FBM and texture as if it was a whole new figure like Gen2. 

Carodan's gallery is a good example of the early V4 renders that really grabbed my attention.

Whether people actually used those morphs or not is another story but with single axis scaling fixed in Poser, the various V4 fixes and the multitude of clothing and accessories available, it will still be some time before she's dethroned.
