There's no justification or explanation. It's simple greed, and that's that. They did it with the ROTJ Fett this year, and they're doing it again. He's consistently been one of the hottest sellers for them since 1995 so they will continue to exploit fans by shaving off the top.
Personally, I don't care. $10 more, $20 more....I only buy the figures I really really like and really really want. If I want something, I'm gonna buy it.
I'm not well-off by any stretch of the imagination, but I have enough left over every month to get some dumb stuff I want, whether that's a figure or a rare LP or whatever.
I think not being a completionist helps. I got out of the "buying out of obligation" mindset years ago and it's very liberating, both on your mind and also on your wallet.
In fact, in all of 2021 the only SW figure I even bought was that "Deluxe" ROTJ Boba Fett, and even that was kind of a spur of the moment, "ah, why not?" purchase.
2022 on the other hand, I already have a few SHF and Black Series on pre-order.
If you look at this action figure and think it looks good, and you really want it....just buy it. It's $10. That probably doesn't even cover lunch these days. Who cares about $10. Just buy the figure!
If you DON'T like the figure, think it looks "off" and that the colors and helmet aren't very well done, and that the SHF is gonna be better anyway, then just DON'T buy it. Just refuse. Do NOT buy something you don't like out of some weird sense of "obligation" to some idea that doesn't even exist!!
