OK I'm not sure if this has been said before, (I'm pretty sure it has) but why aren't there Air and water schools. I mean there are plenty of things you could do for spells and they are basic elements. For example an Air spell Could be like an Angel, Giant Bird, or Flying pigs (lol). Water for example could be a Mermaid, Whirlpool, Siren, or just some Healing water. (In lots of Myths and such water has healing properties)
Just a suggestion. If you can think of something i didnt (That doesnt involve ice, and storm) plz leave a suggetion.
