Less hyperactive micromanaging? Well, I wouldn't exactly say so, it's just squads have less members (full Space Marines squad with sergant have 4 members and 1 heavy weapon, while in Dawn of War 1 it's, I think, 9 members and 5 heavy weapons), there are less squads on the battlefield as well, but micromanagement of those seems a bit more complicated than micro in DoW.
Hmm, when I think about it, I was disappointed in basebuilding - Relic promised basebuilding in MP, so it would be similar to my beloved DoW MP - in fact, you have HQ and you can place turrets and power plants, that's all basebuilding you're going to get. When I was playing MP, I wanted SP - I think it's obvious SP is what DoW 2 is aimed for
