Other than the fact that it is natively supported for both Poser and DS, what are the practical reasons for embracing Dawn for DS? 

I have decided not to purchase G2/V6 because I do not want to buy into that 10-new-base-figures-every-year thing DAZ pushes. 

I have downloaded Dawn and given it a try.  I notice that none of my previously-purchased clothing autofits.  There are minimal morphs.  The Gen4 UVs don't work.  I can't use GenX.  The limitations seem more boundless than the possibilities.

Why would DS users now want to get involved with this?
