Honestly, I don't know what it is with 1/6 figure companies and rubber suits/arms. I mean, one of the main reasons we collect these figures is for the articulation. If I wanted something with no joints and limited or no articulation I would collect statues. It is possible to do joints that look decent without sacrificing much articulation. I really wish these companies would abandon all this rubber suit and limb crap that keeps ruining the figures.
I honestly appreciate the desire to hide the articulation, as I do feel it strengthens the figure's visual fidelity a lot. I also think the rubber suits can be a nice and functional solution. Emphasis on "can". The suit has to be utilized correctly. In this figure's case, their first mistake was actually just using their base body molds under the suit. In makes the shape of the articulation really murky and the limbs themselves just completely fail against the rubber. I would personally have used a body mold under the suit that fills it out a little bit more! That would support the bulky rubber suit just a little bit better.
The suit also needs to go on in pieces, rather than just a rubber jump suit. Really easy to do in this figure's case. They've actually already got a strip of rubber hiding the seam between the top suit piece and the bottom suit piece. All they would need to do is disconnect the leg suit pieces and glue them on independently - letting them move free of the rest of the suit. They need to do the same thing with the arms.
I finally think just gluing the armor pieces onto the suit was lazy practice. This figure would be infinitely more functional if they not only took heed of my above advice of using a body mold that filled the suit out a little bit more and separating the rubber suit at least by limb, but also if they attached the armor pieces to the body mold instead of just gluing them to the suit. They would probably have to either put pieces of the suit on around the armor pieces or press holes into the suit, but I think attaching the armor pieces to the actual figure instead of the suit would have allowed the figure to retain its sharp visual design while also suddenly inheriting a lot of functionality in terms of trying to bend and swivel limbs.
