Archers would be more useful if you could have an "Advance and Fire" command along with troops. It would allow the shorter range units more versitility as well as a few different approaches.

Also a Hold command on Units that you could more easily (ab)use. Right now there is only 1 option with Hold and Fire, you can't hold longer to take advantage of missle fire and in general your Archers with their accuracy are firing on your own troops more often than not if you are routing the armies.

I don't mind not being able to target commander/mages with archers but I do not not like the fact that if you have any archers they either act very idiotic, or if they are long range (Longbow, xbows) they will consistantly fire at the worst possible range even as your army moves forward.
