Since orcs are very powerful late game with the bloodlust, the idea is to make humans a proper early game race with some minor unit stat changes and make Human vs. Orc win rates closer to equal than now, while not making the game feel too different than the original, and while still retaining Orc's late game power, by applying these changes to some of the most played melee maps.
Here are the changes for Humans:
Footman : +1 Basic Damage, +1 Armor
Knight : +1 Piercing Damage (extends to Paladins)
Paladin : +2 Armor (so that upgrading to Paladins is actually useful)
There are no price changes to units or the upgrades, and there are no changes to Orcs.
The maps are:
Garden of War,
All You Need,
Bridge to bridge Combat,
Death in the middle,
Fierce ocean combat,
Forest Trail,
Forsaken Isles,
Great White North,
High seas combat,
Mud in Your Eye,
Oil is the key,
Plains of snow,
Rivers,
Rose Petal,
Schwartzwald,
Taiga,
The Spiral.
You can find the maps in the attachment.
Let me know if you want any other maps, or if you want some changes to make the winrate more equal.
