very true rom.
Another thing is in large scale missle wars (8 archers) i found that its typically more useful to get 6 good archers and 2 bad ones.
say im rome, i would get 6 Archer Auxilia (think thats the name) and 2 Roman Archers and line them up as such.

the roman archers typically take up ammo from their side and guard your good archers front from light cav, now if the opponet is just gonna sit there and arch your 2 bad ones, you dont' lose all that much and it wastes alot of ammo and time.
Another good way to use this is to have your good archers up front, with your bad ones behind you as such

Once an archer war would start, you would move your bad archers up to get pot shots on their army, this start only works against armies that lack cavalry though because your bad archers will take some time to get into range and most likely be chewed up by light cav.
Sorry if i stole some of your thunder rom
