Wouldn't shock absorption be in the mutant class? it's a trait that is always in effect, so it's a trait of your body. Dark shadow appears to be either emitter, as it does create that weird shadowy substance, or possibly mutant, because dark shadow dwells within your body when not in use, and is suppposedly infused with you. Then again, because it has traits of both, and effects your physical body, it's possible that it is a transformation class quirk. Dark shadow is just a confusing quirk when it comes to this topic. It's still really awesome though.

Also, it's been shown that some emitter quirks cause a physical mutation, such as cement. This just makes it harder to distinquish between the different classes.
