Love the magic system they are putting in, however on the flip side to the OP's post is the monsters magical ability and how smart they plan the enemy combat AI to be.
I can see even on easy mode, this being a very difficult game combat wise unless they balance the AI with a fine tooth comb.
I can see for an example, you being surrounded by monsters so you cast rain and an ice wall to halt their advance while you get into position yourself, then some wise guy caster decides to cast earthquake, breaking down your ice wall and knocking you off balance causing you to lose turns while the monsters advance on you.
This could potentially make anticipating the next move difficult. Unless they name the mob "Orc water mage" You should be able to guess what they will do, but if they have access to the same combos the player does, then after say the Orc mage casts rain, your not sure what it will do next. Do you scramble for a dry spot to avoid electrical damage or cast ice confident to trap them in their own spell if they don't cast an ice spell themselves.
Love the system and can't wait to play with it myself in November but the more I think about it, the more complicated it sounds, haha.
