As the Gauls, I found my archers to be devastating. But they are some of the best in the game. I also found Belairic slingers to be excellent. With archers, I was typically getting 180-340 kills a battle. I thought the kill rates were way too high.

I reduced the missile attack values by 1/2 and rounded down for odd numbers. I also increased the shield values of medium and large shields. Value 4 shields, I increased to 6. Value 5 shields, I increased to 8. I felt large shield troops shouldn't suffer too many casualties from archers or slingers.

I introduced these changes in the middle of my campaign. Right now, I am happy with the results. When I start a new campaign with inexperienced archers, i will have a better feel for the effectiveness of archers.

One difference between archers and regular infantry is that archers gain two effectiveness points in missile attacks for each gain in experience. Regular infantry only gains one for one.
