I like Dwarfs they are tough and hard to kill unless you play them like me and go charging into people - especially those with Knights or Sauras Warriors. Played let me see 10-15 games with Dwarves so far and had my arse kicked nearly everytime. Mind you against Empire Knights, and Lizardmen with 2-3 attacks each it isn't easy.
Key lesson learnt from all of these past battles - Dwarves are a shooting army. So with a list composed largely of core units and cannons its best to assume a defensive position and fire away. Me, I always charged full speed ahead, got isolated and slowly cDhewed up. Never a good idea.
