Apparently Amazon shipped the BND Spidey, and he should be here today.
Admittedly, I haven't watched the video, but the idea in general I don't really know about. Legends has felt pretty "above" Black Series for a while now. Granted, the last few waves, BS feels like it's finally catching up a bit, but I don't want or need Legends to change how it's made just to compare or compete. I like each having their own unique identity and feel, with overlap where necessary. Like, would I mind the balljointed wrists on Legends figures? I dunno, maybe. Like with BS, I think it would be character dependent. Both lines are pretty good in their current forms, but both do make some interestingly baffling decisions at times too.
Edit: Okay, I watched the video, and while I get what he's saying, I don't know if it's necessary per se. A lot of it's what we've said before- the fuckery of Disney and the MCU changing their designs, which leads to either cancelled or inaccurate figures, which eats up cost. But especially nowadays, where they're holding off on a lot of live-action figures until well after the fact, I don't want to also necessarily sacrifice articulation on top of that.
I don't collect nearly as many comic figures as I used to, and even then, I keep it mostly relegated to X-Men and Spidey. I know not every figure re-uses one of a handful of molds, but a lot of them still do. So while it may be a bit ignorant to say, I don't know if other sub-lines like the live-action stuff need to suffer when a lot of the quality issues could, in theory, be fixed if they invest in a handful of good, updated molds for comic figures, you know? From what I've gathered, they are slowly starting to update a lot of the older molds like Bucky Cap and everything, but there's still a fair amount of re-use, even if things have gone more pinless.
