Harmony - Troop Symmetry

Resurrection, in itself, is far more important than dealing the same amount of damage, especially when it comes to attrition warfare.

You can't evaluate the game balance based on just one type of gameplay (one type of map).

No one will even bother using a ballista with low damage; why would it need health?

It's fine. Vittorio and others exist for that purpose. But when a ballista is affected by some kind of splash damage, that's not okay. After all, it's an entire hero skill.
