I propose that the tech tree strictly adhere to the following definitions to remove confusion:
Foot Archer: Unmounted archer unit that fires arrows (as opposed to guns or javelins)
Archer: Any unit that is affected by archer armor blacksmith upgrades (including hand cannoneers, skirmishers, cavalry archers, war wagons, ratha, and many more)
What this would change:
Japanese: Cavalry Archers +2 attack vs. Archers → Cavalry Archers +2 attack vs. Archers (except Skirmishers)
Britons: Foot archers (except skirmishers) +1 range in Castle and Imperial Age → Foot archers +1 range in Castle and Imperial Age
Yeomen: +1 foot archer range → +1 foot archer and skirmisher range
Ethiopians: Archers fire 18% faster → Foot archers fire 18% faster OR Archers-line units fire 18% faster
Saracens: Foot archers archers +3 attack vs buildings —> Foot archers and skirmishers +3 attack vs buildings
Mayans: Archers cost -10% Feudal, -20% Castle, -30% Imperial Age → Foot-archers cost -10% Feudal, -20% Castle, -30% Imperial Age
