High PD kinda useless.

I think it is great at choke points. You shove it up to 40 and you have top level infantry. If you back them with a good archer squad they become hard to beat.

I had a 194 man force in a 40 PD provine and was hit by almost 400 troops. They lost 176 to my 1 man. Yes, I was using flaming arrows and had 100 longbowmen. All my infantry was set on guard commander and the enemy troops never made it to my troops. I was planning to make them pay for that choke point and never thought I could win.

Over 1000 troops and two Gods died trying to take that province. I held with minimal reinforcements and just a three or four spell casters. That 40 PD was the best spent money of the game.
