Really, this again?

First of all, its not real elements, some are matter and others are energy, (earth and water are matter while thunder and fire are energy) ITS MAGIC. Not only that but "wind" doesnt have to behave like wind we know, it could be a vacuum or blades, or hell it could just be devoid of oxygen/other gasses and be a force.

I personally like 2 different wheels because its different.
