>>5400922The SHF flattens the upper arm bumps so they'll fit inside the shoulder armour and then has limited mobility when the arm is pointed outwards anyways because of the shoulder armour being so close to the torso (it can get it to just about 90deg to the torso still mind you)
On the figma the shoulder has more separation from the torso and the shoulder armour pivots off the top of the shoulder which gives it less coverage but more clearance and allows the arm sculpt to be uncompromised. That may or may not be related to it having bigger more heroic shoulder pads (my biggest beef with the SHF is it looks a little bottom heavy due to a combo of slightly thick legs and smaller shoulders)
