You do realize that the mountains at the Morrannon were filled with holes, and was where most of Sauron's forces issued from. By the way, chariots were used to zip around the battlefield, throw spears into the enemy, dismount, and fight in a battle line.

If things went ill, the chariots would simply retreat, potentially enticing romans to break formation, making them vulnerable. Then, the chariots could re-engage, with the advantage of a formation taken away if the maneuver worked.
