"Original"

Why are you so afraid of the Ballista units? In the original game, they are weak, especially in the endgame...
You can kill them with one spell, for example.

Who can kill them? A Knight uses Chaos -> Deadly Cold and ruins all their skills just to cast Ring on the Ballista once? Besides, the Ballista is great against neutral creatures.

If you're going to ban something, it shouldn't be just the Ballista...

Besides the Ballista, only Wing and Inga are problematic, the rest seem pretty decent... Maybe Ora too.
