I tested some battles and got some weird results.
2 low cost barbarian swordsmen charged into my high tier pike phalanx from the front, and with like 100 casulties (out of 300 men) they routed my pikes.
Without this mod the pikes almost killed like 200-250 of the barbarians before they routed.
This is too fast for my likes, but there are some really great ideas in your mod
