Personally I think Archers are fine: otherwise HAs would be FAR to OP, the gap between Slingers Archers may be a bit too wide but with those puny bows it's rather clear that they don't to too much damage to guys with armor. Hollywood kinda overrates archers in close to all movies, with the piercing you see in most movies you'd think that Archers must have been the predominant part in every army but infact it's "heavy" Infantry for most, simply as spears and swords proved to be more efficient.
In many Armies bows were exclusive to bunches of highly irregular unarmored "peasants"(or slaves etc) who could aswell have a sling, javelin or a crude rock for throwing.^^

The Phalanx shield is a bit high tho, I still play with it, simply because otherwise Pike vs HA battles are either far too difficult or far to easy, depending on who you play as.
