Which faction do you like the most?

I like the Necropolis and Dungeon factions. I like Necropolis because you can resurrect troops, which allows you to kill neutral creatures without losses, and you can raise troops from neutral creatures. I also like Necropolis because spells that affect the mind (such as charm and berserk) don't work on them. I like Dungeon because of their strong magic and the invisibility ability of their Marksmen. It's convenient for attacking ranged units.
