Poser's weight-mapping tools are fairly easy to learn and it isn't too hard to improve upon mapping that has already been generated for a figure.  It seems to be a bit more difficult to start from scratch, generating a good set of weights for a base figure -- particularly if that base mesh is not well-suited to good weight-mapping results.  I've found Antonia to be a good figure with which to learn how to use the tools, myself.  I'd like to think that the Outfitter could be used as a good starting point to make it easier for a content creator to develop more refined weights.

But creating weight mapped joints can be more laborious than simply adjusting the traditional Poser zone-based joints.  Still, I think it is easier than trying to create JCMs to fix any shortcomings of those zone joints.  I think more people will start using these tools, over time.  Weight-mapping is the future for Poser, as well as DAZ|Studio.  It may not happen overnight, but content creators will begin to use these new tools and options more and more as time goes by.
