I don't think so, Ruby's sneeze left a crater, and yeah you could say that it's because she somehow subconciously used aura but consider this too: Roman was able to blow up a shard of dust with his gun, it made quite the boom. Dust also powers remnant's tech; machines (apart from Penny) don't have souls either. If the Grimm can get creative, they can find ways around the limitations of not having the soul needed to "use" dust in the traditional sense. How frightening is an enemy that is able to learn to use your own weapons against you?
