Is there any reason most of you seem to favor a rifling beeline to a Steel beeline? Is it purely for millitary purposes? Are there trade advantages to the rifling beeline over Steel?
Obviously, the draft cannot be used to get cannons, however I have found it is usually pretty easy to amass a stack of 20-30 cats by the time I pop steel with liberalism. I usually have my treasury at capacity to upgrade 15-25 of them within a few turns of getting steel. Then I usually wage war with CR2 Cannons. The walls go down fast, and CR2 means that about 90% of my cannons live on. I then run cleanup with other units (maces, muskets, or even axes). It doesn't really matter what I clean up with, because with city defenses down and all defenders down to 80% of max, even chariots can handle cleanup. My favorite combination yet has been Drill 4 Oromo Warriors with this attack strategy. The insane number of first strikes of the Oromo generally result in taking no damage when taking on the damaged defenders.
