That's my feeling with a lot of the "QC issues" that get reported on pretty much every new figure.
Obviously QC problems arise from time to time, but the way I've seen some people on video reviews handle their figures it's not too much of a stretch to imagine that many of the reported breakages on the 42 were down to people treating the new joints like they're indestructible.
But as is the way, these types would rather whine and blame the company rather than their own stupidity.
My friend got his 42 a week or so back and I asked him about the shoulder joints and he said they're fine as long as you're careful....so no different to any other figure then.
He also told me that once mine arrives I'll probably view all the non diecast armors in a slightly different light
I think its not too much to expect the joints to work well even with the handling and poses; after all its an 'action figure', one that we paid top dollar for imo of cos
