I will rely more on Honour than Armour. Especially if I'm Oda.

Owari cranks out +1Hon Ashi. Max it up with Legendary Spear Dojos and you can find yourself with 3Hon Ashi pretty quick. With a decent Taisho, you'll have 4Hon Ashi. Pretty deadly.

To top it off, I get them retrained at Omi or Mino for the max Weapons and Armour. I end up with a budget force that's pretty hard to grind down.

Of course, I trade that extra turn for the retraining.
