I don't know how different the ragdolls are between TT and TTR but I think the biggest weakness of it for some reason is not the animated deaths, but as you said I find their weights or something very stiff when it comes to settling on the ground. Because if it was more aggressive with the joint freedom it probably would be abit better, at least witht he arms and legs where they sometimes go stiff at the weirdest points.
It's nice to see someone notice the ragdolls and not be me lol.
