AFAIK the Puck update is basically to un-do some cripples that DAZ made him put into the original and to "de-DAZ-ify" it. It makes the figure easier to develop clothing for and easier to update, but adds no real features to the figure and it's not an essential "fix" for anything. You probably don't need it unless you want to make your own clothing for Puck, then it might be worth the few bucks he is asking for the update. I don't think Dodger is the culprit here. His new Aeon figures are perfect examples of what DAZ could do with the Unimesh if they wanted to, but then you wouldn't need to buy all that extra figure-specific stuff and they would not be able to take your money for selling you the same thing over and over again with a slightly different package.
