I guess if you want cheaper upkeep, and aren't worried about the two-defense differential. That difference of 20 upkeep can add up, as your empire grows. Of course, as your empire grows, money should be less of a concern.
So my campaign went south; fortunately I had two save points, and one was at a point where I was still doing fairly well. I use two save points because I have had campaigns where the file got corrupted and I could not open them again. So it is not great, but better. Instead of going after the Celts like I did (who had attacked me but then keep asking for a ceasefire, which I take because I am not going after them right now and need the money), I went after the Lombardi in Augusta Treverorum.
The Vandals are annoying, they have Spain, so they have numerous large armies. I need Burdigala, but am rebuilding my army to go after it. Arles, where my army is stationed, keeps coming under siege, so it is taking a while to reform the army.
So far, my eastern border is secure, though the Sassanids are getting closer. Not looking forward to that, but at least my infantry is much better than theirs, and most fighting will be done in the cities, so on walls. Yeah, I'm winning those fights.
So overall, I like my strategy. It is a good base strategy, the finer points need to be worked out.
