That combining different mana types actually sounds intriguing, providing the spells were useful. I like ones that fill a gap, such as one to cool the terrain from Grasslands to Plains or Plains to Tundra or add variety such as Law casting Imprisonment. I see Psychic damage being added. Are there plans to do more in that area, such as creating a psionic unit that deals mostly Psychic damage, which would be weak vs Golems and mindless undead. A tier 1,2,3 upgrade path can be envisioned here. Even a mindflayer unit as the archmage equivalent for an evil civilization.
