I think this as well. Lately GIJ Classified had a similar issue, where one accessory-loaded figure came with a pistol holster that holds a silencer but didn't come with a silencer. Another figure coming out around the same time came with a silencer but nowhere to store it. Just a hunch but I considered it the lead guy's way of saying, "this is the best I can do." Just imagining how much worse the ML team has it with Disney involved is enough to make my head spin.both literally cost Hasbro pennies which makes me think they have some unofficial rule about just how much stuff they're allowed to include with one of these. It might not be a case of "Making this extra hand puts us three cents over the budget" and more "we're not giving this character two heads, three sets of hands, and fire effects - that's too much." It got cut somewhere, marketing probably isn't even informed, and you get what you get.
What I don't get, why did they give BW fists + splayed hands, with no gripping hands, and not just do that with Rachel Summers? Very clear that whoever made that decision has no idea what their customers want.
