Rustrazor doesn't get a pass for this for the sole reason that this is supposed to be a brand new Deviant and a base concept created in the previous game and that already has a Deviant itself, is being used as the highlight of its new stuff. Stonefist didn't need to get a Brachydios skull or a Seregios skull to get new stuff. Would have been worse for Rustrazor too if they had just gave it the Glavenus skull from the start and never changed, then it would have only like one actually new attack.

The point is, Deviants are supposed to give us not only a powerful variant of the original monster, but new ideas thrown into the mix. Sure, it may sound cool to make a Glavenus crab, but in the end, it is still a Glavenus crab with the attacks you've seen before many times before used by, the Glavenus and the Hellblade.
