Yes, I DO complain about complexity.

And the reason for all that complexity is that DAZ tries to dumb Poserverse down to make more $$$.
No need to learn how to pose correctly, just flip one of V4.1 integrated pose dials.
No need to learn how to scale, just use one of V4.1's "morphforms"
No need to learn how to compose an expression, just use one of V4.1's built in expression presets.

It's all so utterly "convenient".

It's like fitting every car with an automatic transmission because SOME people can't be bothered to learn how to shift.
Or turning every ISP into AOL because SOME people are scared of the WWW.

The result of all this "dumbing down" and giving you a "better Poser expierience"?
A mesh that is way more complicated internally and much more prone to breakage.
V4.1 is Murphy's Law in action, but people only see the new shoulders and the sexy default bodyshape.

And no, more parts does not mean more flexibility.
Seperate buttocks, good. Seperate waist, good also.
Double jointed shoulders ? Not really usefull any more.
Seperate teeth and fully articulated tounge ?
Absolutely not worth the hassle.

BTW, NaNaNa is a custom head or a morphed A3 head on a V4 body, so there is no need to re-rig anything.
But try putting V4.1's head on A3's body and keep all her erc controlled head morphs as well as the teeth and tounge rigging, that's when the "fun" starts.

I couldn't care less about what program or what meshes anyone uses, but the Poserverse DOES spin around DAZ and the latest V-Chick.
So if DAZ makes it too hard to create free textures for V4.1, then there will be a lot less free textures, period.
And if all the newbies get suckered into joining the D|S bandwagen, a lot of hidden talents will never have a chance to develop.

You seem to share DAZ cynical stance that just because only a few people actually use the options that Poser gives them, they should be taken away from everybody.
But people can stick to using nothing but premade content  just fine in Poser.
But IF one bright day they wake up and say to themselves:
"Hmm, all those face morphs really start to look the same to me. Let's see what this morphbrush thingy can do..."
Then they have all the tools readily at hand to become creative themselves.

In D|S, as it is now, this simply won't happen.
You either make do with what DAZ thinks is good for you, or constantly plead in the forums for some of the "professionals" to do it for you.

A cage is a cage, even if it comes with golden bars or a fancy "modern" GUI.

And for my creativity, D|S IS a cage, because it doesn't allow me to do the things I want.
