Mongols are supposed to be the kings of horse archery but Mangudai are always nerfed because team games and they feel terrible to play. The civilization know historically by their hordes or horse archers and pillaging is played as a tower rush civ.
Proposed chages:
SILVER TREE
-now also spawn a 1/2/3 free mangudais the first time each tier of the Silk Road is reached in the game. Additionally, the Mangudai gain 1/2/3 out of combat HP regen every 5 seconds for each level of the Silk Road
DEER STONES
-Now also allow Mangudais to be trained at stables and reduce their stone cost by 20.
IMPROVED PROFESSIONAL SCOUTS
-Allow Scouts to GATHER food from boars and berries at 0.8 gather rate of villagers, they have a carry capacity of 30 and get slowed by 0.01 tiles per second per each food unit carried. they can ONLY drop off at town centers
