The melee general lost his use with the Fall of the Samurai, guns are just the way to go. But if you play against Shogun 2 generals a melee generals has is obvious advantages.
You don't need legendary retainers to make him useful, but they certainly give you an edge, like +10 attack. I had this setup, a melee general with all points except for morale spent in melee + a bow with extreme high missile damage and armour penetration.
This general is excellent in combat and makes an invaluable harassing unit because he can take out even the heaviest soldiers with a volley (up to 6 soldiers of the generals bodyguard with one volley).
Too bad FotS made him utterly useless
