Personally, I can't stand the Dwarves. Their idiotic laughter when they manage to take down a stack really annoys me. And in general, I hate that they're overpowered in the late game; Inga with a couple of castles is already too strong. It would be better if they made the Necropolis and Inferno factions stronger. And by the way, I like Archdevils; unlike many here, I think they're stylish and powerful. It's a shame about the other units in Inferno, though.
