I don't mind the "management" part of the crusade, it is not very different from kingdom management in PK, and the main character is supposed to be the leader after all.

The army battles on the other hand are disconnected from the rest of the game in a way that feels a bit immersion breaking. I have a mage general who, after gaining a few experience levels, became some sort of superpowered entity. His spells do 5000-6000 damage and decimate the enemy armies in one-two casts. He is so much more powerful than my character, her party and frankly the entire crusade army, it is hilarious.
