As I said Scar, it depends on the rules that are being played, for example: "NERTHH" rules mean no rushing(no attacks for 8 minutes), and turrets are not allowed. I'm not sure what you mean by the "harvestor mowing the scout at refineries", the stealth raider cannot be run over. If you put it in the spot where the harvestor has to go to empty the spice then the harvestor will just stop and do nothing patiently waiting its turn to go to the refinery. As to you kicking my butt with your infantry, I have two words for you...SEIGE TANKS!!
