Which faction do you like the most?

I personally like Necromancers, Demons, and Orcs. I like Necromancers for their ability to raise the dead, and it's interesting to build up an army with them. I like Demons for their heroes and Demonesses, who can attack multiple creatures at once and retaliate. And I like Orcs for their originality: they don't have magic, but they have battle cries, and I also like their assassins/executioners/chieftains.
