A petition? I can't tell if you are serious or not!
That head sculpt is one guy at home true, but how do you know he is not an engineer or an artist? He could easily be both. Nevertheless, he made one great head. Could he make 1000 of them exactly the same, and not take years doing it? Not a chance. And he sold it for $39, how many would he have to make to use that as a living? And if he does it as a side business, how slow would it be to keep them coming in the numbers Asmus do, while keeping his day job.
I am sure there is a guy/girl in the Asmus factory who could have done the rooted braids and hair for Legolas, but it doesn't mean its possible to mass produce them with any accuracy or consistency. Which is why they went the way they did.
As for the hobbits, personally I would like them rooted if done well, but its just not feasible yet. I am sure it will be eventually as skills and technology develop, but Asmus is still a business and they need to find cost effective ways of making the best possible figures vs the cost vs the ability to reproduce the results consistently.
You also have to consider that not every one feels the way you or I do, many prefer sculpted over rooted so again they have to make what they think will sell well.
No amount of requests from a few people on a forum will ever change that. We are lucky Asmus pays as much attention to as as they do.
