Personally, my favorite playthrough had 3 nimble fighters for tanking, a similar number of archers, two hornblowers, and everyone else was a two-handed weapons guy. Everyone that was offensive had Perfect Focus and just smote things while the Nimble guys kept the enemy distracted.
Worked pretty well. I plan to do it again, maybe fudging with the number of nimble fighters.
I’m actually working on testing out Danubian’s strategy in my present playthrough, but haven’t had the time to go far yet.
