Most of you seem to have completely missed the problem. Archery units can kill firearms units in 1-2 attacks and take zero damage while doing it from 2 hexes away. The very least they could do is let the gunpowder guys fight back, these units are just plain useless the way it is now. I just marched my minutemen to an enemy city and I had about 5 units just wiped out without even being able to attack once. Pikemen are superior units than musketmen/riflemen and are much cheaper to produce.
