I'd rather let them sally out (the fact that the units come out one at a time seems to be advantegous to a faction who relies on archery such as the Parthians).
Now obviously the whole point of the Parthians is to use mounted archery tactics. So what I usually do is I will focus all of my fire on one unit. I demoralize them by doing this and when you have 10+ units of Horse Archers firing on one unit, the enemy unit will be gone in a few volleys - especially so if you are using experienced units. So unless the case of a full stack attacking you, you should be able to rout the entire army. Now, this is the AI I'm talking about - the AI is stupid, and any real player probably wouldn't wait around to get shot as if it's something fun. So honestly my massed HA technique is nothing to be amazed at. But in this way I've barely lost any battles.
If your men run out of ammo, you could just head for the hills and end the battle with most of your men. But if the army is experienced enough, I will sometimes just do a mass-charge at each individual unit to make them rout.
I'm not sure if this strategy is slightly different or exactly the same as everyone else's, but either way I figured I'd post it.
