So after giving me hell for weeks I finally settled on a strategy that has allowed me to complete this one. I went RoK and Bambur plus a commander has single handedly crushed every other empire along with some Air 2 Mages. I never bothered taking any cities, as my stack moves across the map I just raze everything to the ground. I am disappointed that Beeri was the first leader to be eliminated. How much story will I miss out on by not joining with him against Perpy?
