I'm liking what I see of the game so far, but I really feel it is missing the boat on resistances.
For instance, a fire spell should do more damage to a water creature or even a mage who specializes in water. Some of the things that could be done with this is something like a water spell healing a ice elemental, or a fire spell healing a fire elemental. This could even extend to some creatures being immune to materials of weapons as well.
I think this would add a lot to the over all feel of the game an a ton to the tactical battles.
Thanks for reading.
