I would really like to see some spells that stay on the field of battle as long as they are in effect. 

1. Enchanting a unit should make them glow or shine so that it is readily apparent and awesome what has happened during a battle. 

2. I would like to be able to block large areas of the battlefield by summoning a vortex or lightning storm that stays there for several minutes. 

3. Entering an affected area should start a new animation to show damage to that unit. 

4. I really hate it when the damage is shown above the head before I see the magic animation.

5. Since I am wishing, I wish for dead bodies to fall and stay on the battlefield. They should be reanimated into zombies. I understand how ridiculous that is based on how the game has been made.
