I still don't see why the light-bending illusions, even with updating them, would cost nearly as much energy as the physical movement that Ruby does. Also, the light needs to be constantly projected for an appearance to be maintained, otherwise the effect would cease to work, as light moves. Assuming they both have an aura of about the same intensity, the way you would compare the cost is very similar to a small movie projector versus an electric motorcycle. And one other thing. Regardless of the other stuff, why doesn't she just make a big square of some random color in front of her opponent's vision when fighting someone? She could have made Yang into a blind flailing angry chick and beat her much worse in that one battle.
