This patch is a alternative to D2682.
The proposal is to balance the health of the heroes. Some civilizations like athenas have only infantry heroes, who have 1000 health, being at a very big disadvantage versus civilizations with cavalry and elephant.
Without patch:
Healer/Infantry 1000 health
Cavalry 1500 health
elephant 2000 health
With patch:
Healer/Infantry 1000 health
Cavalry 1200 health
elephant 1500 health
The patch not only improves the disadvantage between civilizations but also some major problems like elephants mega tanks, cavalry that can join the enemy city, kill many women and leave alive, and also improves the experience in regicida and regecida/nomad maps.
