I rarely look at the JP forums, but I did a search for this and found ONE person who requested it. It was posted in a thread regarding character appearance.
It was posted about 1 year ago. The thread is only 1 page.
Thread here.
This person says "Although many things have already been well said regarding character specifications, there is one thing I would like them to do even though I know it's impossible.
I wanted them to make it so we can adjust the size of butts.
The female character's butts are too small.
Such a small butt is not attractive"
The post only has 14 likes, which might seem small, but on JP forums it is not rare to see posts with almost a hundred of likes. So 14 is very few.
But, on JP forums people do not make 10 different threads about the same topic.
For example, there is ONE thread for "Requests".
So, basically, everyone puts all their requests in there. There are not 10 threads on the same topic. Because, why?
There is another thread for "idle talk".
There is a thread for "I want them to fix this for 4.0" and "I'm glad they fixed these things" and some threads about Fan Festival.
To give more perspective, on the first page of "General Discussion" the oldest post was 11-05-2016.
To last post on that day on these forums is Page 11.
The JP forums and these forums are a very different place.
