Right, I have no bullshit defense for this one. You're right about lowest potential difference, and the current tends to want to go down to the ground. But actually,
if electrokinesis was about changing the potential difference of certain specific objects, then that would make a lot more sense, as the target would act like an attractor to all that electricity. But then it should be getting sparked by other sources of electricity.

The light element is another one which often is used for healing. How does light heal anything either? How does blinding you with-ah fuck it.
I give up. Light isn't physical, so beyond burning out all the cones and cylinders in your eyes it can't actually hurt you. Well, maybe burn you if it gets intense enough, but that's just because of the amount of energy and it starts getting into fire territory. The healing thing could also be symbolic - light breeds life - but whatever.
