Though with the Greek Cities, do you just go with your phalanx and cavalry? I usually like to hire some mercenaries like mercenary peltasts or something for flank protection.

By the way, while still on the subject of the Greek Cities, do you use militia cavalry? I always have at least one unit on a medium- to large-sized army-- it helps a lot to be able to chase routers with them and conserve the breath of the general's bodyguard.

Plus, they are very fast, meaning they kill routers so much more efficiently than regular cavalry. I usually start the battle with fire-at-will turned off. In some battles I don't use the javelins, or, indeed, the militia cavalry themselves in actual combat, but use them to wipe out routers. I find them especially effective in assassinating routing generals.

As missile cavalry, though, they suck spectacularly. Low range, ammo that soon runs out, and not significantly more effective than horse archers in men killed per volley.
