That is probably because your rigs are too good and you already put a lot of time into them. With such a doll, you would only need a simple FK rig, since everything else is kind of built into the doll. Considering this i can imagine this being a real time saver. But i would need a whole battery of those dolls, at least for humans, dogs and horses, so it likely is only a time- not a money-saver :-)
