[@Dark Light][@NobodiesHero] Both sound good to me!

A little note on the sub-elements: If it makes sense for it to be in the domain of your major element, then it is fine for a sub-element. So while in Avatar lightning was a subcategory of fire, it does make perfect sense that it would be a part of air.

So for anyone else coming in to look at this yet; Fire, Water, and Earth are available still.
