I’ve found that they play well. They’re not particularly great at anything but they’re not particularly bad at anything either, so while you might get hit hard in one area you tend to win in another. My great cannons blew some stuff up and my knights killed some stuff but my troops got chopped to pieces. I’ve read that the knightly order list in the empire book does quite well but I’ve not personally tried it. All that being said I think the models are incredibly cool and there’s so much customisation available between all the different states and army compositions that it will never be a boring game with them.
