This post doesn't mention any skills that you're talking about, and I don't think guns really need to have their scaling for things like Demon Hunter Reaver skills, since you're using them in an impractical way.

Does this mean bows don't get scaling for Reaver skills as well? It is the same argument, I just don't have an archer to test it.

Though, Cripple Arm/Leg definitely should at least have their scaling if they don't already.
