This is also an interesting strategy, but can also be very dangerous. I've played multiple Generals and often my strategy depended on the situation and my enemies. In the case of Sirion now I chose a very defensive strategy, let the enemy make mistakes by being overconfident and then creating the upperhand slowly but steadily.
Concerning my Marshals I was forced to give them more space than I've done in the past for instance. But that was also because my General was a very young char and the Marshals very respected nobles.
I'd adjust my unit settings to my enemies, but not my strategies.
You'd be surprised how often the same armies re-use the same unit settings for every single battle. If you know how the enemy will deploy, you can use it against him.
