The strength of the whole TW series has been the combination of the strategic campaign and tactical battles. The campaign is the province of SP play, but the tactical battles must benefit from input from the MP scene. I don'y play MP - barely have time to do SP - but both parts of the equation is important. I get the feeling that the quality of the campaign game has been second best in the rush for good looking graphics - but that is not down to MP I think. I don't think that excluding MP would necessary address that.
