In a recent game, I noticed that the AI had chosen to Guerilla 1 promo for their archers for the cities that are built on hills. I had never thought of it before, since I always chose City Garrison 1. After looking at the promotion line, I realized that it made total sense since when promoted later, Guerilla 2 gives an extra 5 percent (+30%) as apposed to the +25% for CG 2. It also allows the extra movement on hills and even allows you to fight back if promoted further since it Is this a good strategy to use, and am I missing anything?
