Err, no edit...

I ll give some back ground.

It's the 220's and I am in war with the Seluceds, Parthians, Romans, Numidians.

Now every city has stone walls or greater and the Roman cities are all guarded by Archer Auxilia and Legion or Praetorian Cohorts. The Partians guard their cities with MASSIVE like 2000+ archers and horse archers. I dont have time to fight the numidians because of how my empire is soo stretched out right now. The Seluceds have one city left but it's guarded by 2 generals, massiv archers and phalanx pikemen (almost full stack so close to 3000).

I ve tried to assult these cities but my units often rout before they actually can reach the enemy within the walls! Siege towers and rams are useless as they get shoot dead before they can even reach the walls.

Need advice.
