Completely agree with your two criticisms. I forgot to mention the forearm kibble. I was furious with it at first, before I realized there were two elbow rotator cuffs, one immediately below and one immediately above, making it pretty easy to get out of the way.

I find the lack of wrist articulation to be a glaring omission. There doesn't seen to be any structural need for it, so I assume it's cost cutting. It makes awesome knife poses difficult.

Lastly, the ball joints holding in the front corners of the alt mode/chest are hopeless. I've learned to compensate by holding the balls in place when I transform that part, but it really should be better.
