Does anyone use archers for offense. I think archers are one of the worst units in the game but they haven't been mentioned in recent polls. If you try to attack a spearmen fortified in a city you will nearly always lose. The time frame in which they are the best attackers is very short. I usually will have at least horses or iron in my territory. Horsemen and swordsmen are so much better. In my opinion even man -o- wars are better than archers. Unless you want to take your ships half way across the world to attack a strip of shore line and maybe take off a shield or two in production of an enemy city.
For Coastal defense man-o-wars are great. I don't know about you but in early wars my production isn't very good and i can't handle half my attacking force getting wiped out taking an enemy city.
