Well... What use does the Naiad and Freak Lord have? The *****queen? The Lich? The Mother of Monsters?
I realize I'm inexperienced, but there just seems to be some options far more attractive than others, and the element of surprise doesn't last long in a turn-based game
Other than that... Maybe a few more spell animations? Some spells don't look very much like what their description says they are. And perhaps up the movement speed of magical projectiles. When you have 10 mages per side in a battle it takes quite some time for those Storm of Thorn's to land : P
Another thing I'd really, really want to see is to have the sound looked over. Some sound effects are just unnecessarily loud (especially since they "stack"). Some hurt even from just one unit shrieking (HYDRA!).
