You know, I really don't get the reluctance for using the term "power creep." The early uniques are much less powerful than the current releases, right? Can we all agree on that?
I get that some of the problem might be "over-costing" for the originals, and sure, that is a big part of it. If Vader were 10 points he would be used much more often.
But if we cannot justify taking one figure (or figures) because they are not worth their cost when compared to newer figures, that is what EVERYONE means by "power creep." No one is complaining about Bossk being completely unusable. Everyone is complaining about Vader and Han. It is not coincidence that the unusable uniques were released in earlier expansions, it's systemic. So the early stuff is not as useful as the newer stuff, and without a fix they will never be seen again. That's... like... the definition of power creep. (Is it just the fact that it only applies to the uniques????)
Power Creep by definition: Compare the current meta game to new releases. The new releases are better than the current meta => power creep. The new releases are not better than the current meta = > no power creep!
The majority of the older uniques NEVER have been part of the Meta. NEVER! The Meta was 9Act and Vader's Finest, then 4x4 (and some Sabs to conter 4x4), then Twins, variants of the Trooper spam and Bantha / Beast Machines. The only older unique I've seen win tournaments was Gideon.
Therefore, by definition, this is not power creep.
