I don't know about everyone else but I am happy that A4 can wear v4's clothes and use her morphs. I'm a pc member so i got her for free and as a college student I wouldn't have not been able to afford A4 if she were completely her own figure. A4 gives me more facial and body options so I can create a greater variety of characters and her head can do things that v4s couldn't. So I still can't figure out why everyone is complaining.

   Firstly, as thefixer has already pointed out, nobody is "complaining", as such, but, if there are grounds for complaint, I think they may come down to the way the DAZocentric side of the community has tended to deride Poser's corporate owners in the last year or so for using standard G2 male and G2 female bodies, with only the heads differing:  James, Simon, Koji and Kelvin for the G2 men, with Jessi (not to be confused with the vastly inferior Poser 6 Jessi) and Sydney for the women.  You mention the extra versatility of A4's head, but, let's be honest, the average balloon can do things that V4's head can't manage.
