We know that and Pyrrha explained it. Hunters have aura and they can train it to increase their options about how using it from creating forcefields to increase their strength (punch harder, jump higher). Weiss is a good example of the art of combining dust, aura, semblance and a weapon.

Weiss can use her semblance to create glyphs which are connected to the weapon through her aura and mix it with dust to change her powers. Monty said so himself, Weiss' fighting style is more disciplined. Ruby on the other side, she is a lv.1 dust user, she buys the dust bullets, loads her weapon and shoots. As simple as that, she only wields her aura as a forcefield to prevent damage while her semblance allows her to swing her weapon faster.

Also, I agree with Darkcloud. I don't think we should consider Weiss' abilities in the White Trailer as cannon since the fight itself was kind of an inner illusion. Besides, she has a lot of powers in the trailer which could have given her victory so easily in other fights in the actual volume yet she doesn't use them.
