One thing that strikes me a lot when I use V2 for something as I do from time to time:

If you buy a clothing set for V3 today, you expect as a matter of course that there will be at least some support for the main V3 morphs. So if you load up V3 and give her "Barbarian1 = 0.5", you can dial the same morph into the suit she's going to wear.

Not with V2. The clothing that was sold back then almost never had any morph support at all. Of couse, you could still use things like VV magnets, but generally, it seems less work went into V2 products.
