Okay, so, that's how unit strengths
stack up. But these units also cost production, which certainly comes into play. Let's dig into that now.
I'm repeating what I did in this post
. Read it to understand methodology. The gist is that given strength & cost, two units can be compared to determine how efficient an upgraded unit is over its precursor. The important point about strength is that in combat, +X strength means both +Y damage dealt and
1/Y less damage received. So strength confers advantages on two sides of the coin- hence a unit that had +17 strength does double damage and takes half, resulting in 4x the combat effectiveness. "+17 strength, you say? That's what an Army formation gets, but it only costs 3 units for the power of 4?!"
Exactly- that's why Zulu is OP and military academies are extremely powerful production structures.
Anyways, let's go back into the land unit lines:
All unique units are compared to their predecessor, but in all cases except the khevsur, the next base unit is compared to the earlier base unit. E.g, tanks are compared to knights and not rough riders.
