Supplies reduces the cost of the Champion line by 15 food (25%). Many pros (and normal players) have pointed out how this reduces the viability of many infantry units (such as the Woad Raider or Samurai), because you might as well just go for the Champion (which is cheaper in both gold and food cost).
Parthian Tactics affects the Cavalry Archer line and certain Unique Units. However, it has a greater effect on the Cavalry Archer line than it does on the Unique Units. Supplies could have a somewhat similar mechanic (where it reduces the cost of Champion to a greater extent than it reduces the cost of Unique Units).
If Supplies reduced food costs of Unique Units by 10% then:
Alternatively Supplies could just give a flat -5 food cost to Unique Units (*laughs in Karambit* (Although, to be fair, Karambits did cost -5 food AND -5 gold when they were released, and they aren't exactly OP right now))
