I have noticed with the Persia and Japan patch that the Ottomans do not like to merge their armies together. They keep their armies with 1-4 units per army and they each follow each other. I haven't seen any other AI country do that but the Ottomans. So I am wondering if other people have been experiencing the same problem I am having. I am starting to think that these small armies all moving together are slowing down the game, so speed 5 feels like speed 3 or speed 2.
