Doc, I had a similar thought on the "ban". Disney kind of came out of the blue with it... Revel immediately put out even a press release denying they said anything, and that they welcomed Bandai on the shelves in the US (more the merrier kind of thought). I think they took some serious flak right away. People just assumed and it's tough to argue.
Hasbro's taken shots at Lego over the years, so I'd not be shocked in the slightest if it were they who actively asked Disney to step in and enforce this. These 1/12 kits are still kits though, but either way Bandai isn't a US property and so on. They make one HELL of a figure though and ultimately they require very little painting (sorry about your hands... My mother's shake now a good bit, and I've been dealing with an issue since August that has impacted my ability to simply build a kit actually. I have to take baby steps now because of focusing issues).
I've really taken to these though. I didn't buy any 6" Hasbro offering but Bossk... Bandai's kits though, they were so cheap on HLJ I figured why not? So I got the droids and Stormie, and it just rolled forward from there as I really didn't want to buy 6", and I don't feel compelled to support Hasbro pushing 6" as a format... Kind of my lame political stance, haha.
But yeah, I mean these kits are insane, they're detailed (more so than Hasbro's figs), they're poseable, they're infinitely more customizable IMO as they're designed to be painted unlike Hasbro's plastic type. Just all around I prefer them. I wish they'd do less armored or droid characters and look at "real" characters. I think they have the ability, even eye decals are a thing, so painting shouldn't be much of an issue there.
That said, I've contemplated Figuarts figures as a means of staying away from Hasbro but still filling out some of this scale with main heroes like Jedi Luke and so forth. Not sure how the two compare to one another. Kinda curious really.
I've seen comparisons done with Hasbro's stuff, and gotta say, their Vader and R2 are laughable. X-Wing LUke though looks great WITH the droids. Just perfect. Bespin Luke as well.
