Dwarves suck to play against. It's not that they're hard to beat, it's that every game is the same, and I'm not playing Bloodbowl as some hyper-optimized, serious board game.

Most my Bloodbowl happens online, so if someone's playing a Chaos kill team or a Dwarf team then I'm probably not going to play them. Games take well over an hour to finish. I'm not going to sit through something that makes me miserable so some giga-nerd can jerk himself off over his brilliance of putting guard on every one of his players.

Is something inherently wrong with the faction? No. But I'm playing to have fun, and I can't do that if I'm playing against dwarves.
