Strange. I recently bought the game as well, but while I loved the DoW I campaign - well, the dark crusade "campaign" most of all tbh, the DoW2 campaign doesn't quite cut it for me.
Perhaps it's just that I"m not a huge space marine fan (Orc! Orc! Orc! or Eldar! Eldar! Eldar! or even Imperial Guard instead...) but I'm finding the campaign rather one-dimensional up till now (first 7 missions played or so)
Also, does the game only allow 4 (5?) squads to be controlled in MP as well, without options like constructing buildings? The game feels quite simple so far (use cover, have squads cover each other's asses and go back to these radar-antenna points regularly to have your units returned to full strength)
