So I decided to test my modifications on a custom battle: The setting was Ordona Plains, Summer, Clean, both armies were randomly generated (althought I took out Ranch Animals, Artillery and Gunner Posts and replaced them with other units so that the maximum florins expense would be reached).
My army (notice the unit sizing):

The Ordonian Army:

Both Labrynnian Elite Infantry and Ordona Cavalry costed more than the rest of the army.
Since we are a defensive faction, our formation is important:

We're on the northwestern hill, cannon fodder is deployed in front to serve as pillows against cavalry. Behind them, in the centre, there are Schiltrom Homeguards and Shield Wall Palace Watch to fend off enemies. Behind them there are Borderguards, to shoot enemies from safety and Knights of Ambi that will be ready to attack any moment. I send my Pathfinders forward to snipe cavalry:


They're marching westward to face us frontally. I would tell them to fire at the Horsemen, but I don't like the Archers and Rangers standing between their target. Let's aim at those and see if they react:


We managed to take out... not enough; they don't even flinch. In the meantime, Horse Archers spring from the army's rear. They'll make a better target...

Sir, what do you see?

It seems those incompentents can't even sustain a shootout with mounted farmers.

Maybe their wooden crossbows jammed...

Crossbows? Weren't they shooting ballistic knives? Sound the rally!

Here they come! Cannon fodder, charge!

They couldn't even graze them. It'll take more to arrest the might of Ordon browsers.

The fight proceeds: My infantry held them off perfectly and is now counterattacking, but my Pathfinders are being chased down by Horse Archers and they're almost all dead. My Borderguards weren't being much effective shooting parabolically, so I tried moving them in the open by the flank. Needless to say, they were chased away by a mob of fat Ordonians angrily swinging their hatchets; but at this point we're already repelling them.


We're taking down Goat Lords, but Horsemen attack our crossbowmen.



They finally rout, but the loss of our Pathfinders left us unable to chase them down, therefore we only get an Average Victory; it's nevertheless a big step forward from the overpowered Ordonian Heroic Farmers and underpowered Labrynnian Cops.
