Passive doesn't need to be a non-fighting skill. Technically, Yang's Semblance could be counted as passive since she can't control its activation. You could have a passive Semblance that increases the user's strength based on adrenaline think this one has been done before.

Your Semblance isn't bad. The Dust interactions are quite interesting. However, like Spirited said, many things the Semblance does can also be done with the use of Dust. If you feel this Semblance is the perfect fit for the user you have planned for it, then use it given there are no glaring problems. Most people on the thread just discourage strictly elemental Semblances because most of them are just Semblance versions of Dust use.
