Why am I not able to win the Orania Map ?

Of course, with nations with solid PD ( Jotuns especially, but also Ulm & Abysia, etc ) there are some interesting ways to use high PD values. For example, when I've been positive someone was about to attack a particular province I had a good army in, I've cranked the PD up to a very high value (35-50) just as I'm expecting them to attack.

The PD then soaks up the bulk of the casualties for me (troops are all moved to the rear) while mages are buffing the troops with all the good things like body ethereal, legions of steel, mass regen, luck, etc. The enemy troops and mages get tired going after the PD, and then have to deal with the real forces. In theory, this results in very light casualties for the army, and the PD regenerates after the battle.

I use same tactic whenever possible. Actually I use it with nearly all nations as they can soak damage just as well. Those you mentioned are best for the job though.
