My armies tend to be heavily spears/naginatas, katanas, and some monks now I'm Uesugi. Plus a few cavalry, and a few archers. I love melee, though if the enemy has lots of archers I prefer to let them come after me. Archers being a bit dumb doesn't help their cause. If they won't come to me, I try and get my units as close as possible while getting shot up as little as possible. Once in hand to hand range I'm normally ok.

My brother as Chokosabe had 100% samurai archer armies. He found attacking was sometimes problematic.
