Since you're not going with the Master of Magic spellschools of Chaos, Nature, Sorcery, Life and Death you must either really believe in your spellschools or you want some new things. So, convince me why this new system of yours is better

I was quite surprised to see that you're going for more schools rather than fewer as i envisioned the Master of Magic spellschools to be the original and best. I was disappointed in the Age of Wonders series for going with Fire, Earth, Water and Air.
I've always seen Sorcery as the most fun school there is. Just imagine a multiplayergame where you constantly dispel your enemies summons and enhancements while they can't (easily) do the same to your Phantom Beasts and Skydrakes.

I know about the crosschoolspells.
