I thought about that as I typed it.
They changed that image for ratskins, just before they pulled SG development, into more generic post-apoc barbarians. I'm still not sure if it was a great idea, removing any (most) iffy stereotypes, but sucking the flavour out too.
I think you put your finger on the problem with the "new" Ratskins... Along with awkward posing, I didn't think particularly highly of the Fanatic/Specialist Games re-sculpts for Necromunda.
The best were definitely the Goliaths IMO, as they actually had some nice models that fit well with the original aesthetic and gave players flexibility with regards to weapons. They also got much better Juves this time around, looking like Keith Flint from The Prodigy.
Close second were the Enforcers, which were not-Arbites-and-definately-not-Dredd, but looked quite good nonetheless and had fair weapon options too.
The worst were harder to choose, but include: Scavvy ghouls/dogs, Ratskins, most of the Redemptionists, most of the new bounty hunters.
The new Orlocks were
okay I guess, but were totally different from the Perry originals. The new Van Saar were a reasonable match style-wise with the Gary Morley originals, but so-so heads and awkward poses spoiled them.
Mostly though, I didn't see the purpose in re-imagining the established models. Aside from being a dick move to those that already had gangs, they would have done much better if they had simply added more options to the original range (which had few melee and special weapon options on the whole).
Then again, their approach to the minis was the same as the rules - fix some stuff that's moderately inconsequential, ignore the parts that definitely need a lot of help (like the wonky quality of the various skill tables).
