There are a number of wands that could have really cool animations, but don't. Why? Who knows, but it sure would be nice if they were revamped. With new animations, and camera effects - zooms and so on.
Here are a couple to start off:
Lighting bolt - dropped by Zeus. It could have an animation where the user rares back and flings a crackling bolt of electricty across the battle circle to splatter on the target. It doesn't. Instead, it has the mundane, boring staff animation.
Flaming skull - Road warrior pack. It has flames dancing around it's head. Those flames, or maybe lasers, could shoot out of the eyes to do damage. But no, it has no animation at all. Just the standard low level wand animation with the damage animation based on whatever school it is. Boring.
What wands to you think could benefit with new animations?
