Harmony - Troop Symmetry

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

Based on what specific type of gameplay or map? Are there maps where there is no breakthrough and resurrection is not needed?

It's normal. Vittorio and others exist for this purpose. But when a ballista falls due to some kind of splash damage, that's not okay. After all, it's an entire hero skill.

We were talking about increasing damage in the context of moving firearms into the machinery branch, into the catapult branch, i.e., about an alternative (mutually exclusive) branch of development from multi-shot.

A typical ballista is only effective when multi-shot + firearms are developed; otherwise, the damage is not good. If we remove this combination, we need to ensure the same level of damage for the multi-shot branch (without firearms) and for the firearms branch (without multi-shot).

Or are we talking about the fact that the ballista is too strong in general and needs to be weakened in terms of damage (relative to the firearms + multi-shot development)?
