NOT to burst your bubble but some off these schools are exactly like the ones we have already with a few changes but still so similar so some of these cant be added. Also the craft and gardening are already added to the game. Although the alchemy schools sounds promising.
All the schools connect to alot of things in the world like:
Life goes along the lines of: Trees, gardening, flowers, rocks, animals, music and stuff like that
Ice goes along the lines of: water, freezing stuff, cold weather
Storm: rain, water, lightinng, thunder, hail, wind, and other things.
Death: spirit, night, silent, such stuff like that.
Myth: chaos, maybe craft, maybe such things like that.
Balance: plague, wind to, dry weather, rock does to, its pretty simple.
Fire: Hot things, rock, magma, ash, and things of that nature.
So you see all the schools have to do with things like these they just broke them up into these schools becasue these are the best way of decribing things like this.
