Agreed. Dawn of War 3 should be just utter destruction between every possible WH40k race across the whole universe. With online co-op campaign. Conquer the universe in the name of the Emperor or Chaos gods, suck all life from it for the Hive or just annihilate every sentient being for Necron gods (if there are any), defend the Imperium planets as Imperial Guard and Sisters of Battle or fight for the Greater Good, loot the universe for da WAAAAAAGH!!! or be a witch and try to burn the worlds for the Craftworld. And then there are Dark Eldar.
