Unit cards:
28 land unit variants have a different unit weight category on their data cards than their actual soldier/mount weight would indicate. This means people were assuming things about their speed and performance in a charge than were really true. Simplest change is to bring the cosmetics in line with the reality. Units affected:

Celtic Warriors (weight was given as heavy on card, but light in reality)
Aux and Merc Dacian Skirmishers (very light on card, light in reality)
Aux Eastern Horse Skirmishers (very light on card, light in reality)
Aux Ita Socii Hastati (heavy on card, medium in reality)
Dacian Heavy Skirmishers (very light on card, light in reality)
Parthian Horse Archers (light on card, very light in reality)
Suebi Hex Bearers (medium on card, light in reality)
Suebi Horse Runners (light on card, very light in reality)
Suebi Night Hunters (medium on card, light in reality)
Suebi Round Shield Swords (medium on card, light in reality)
Suebi Spear Brothers (heavy on card, light in reality)
Suebi Spear Levy (medium on card, light in reality)
Suebi Tribesmen (medium on card, light in reality)
Italian Noble Cavalry (heavy on card, very heavy in reality)
Italian Spearmen (heavy on card, medium in reality)
Thracian Royal Cav (very heavy on card, heavy in reality)

Wrath of Sparta:
Baktrian Cav (medium on card, light in reality)
Hippeus (Greek, Theban, Thessalian) (very heavy on card, medium in reality)
