I think supporting ops are one of the most forgotten elements of general strategy in the Mains. You'll see a huge gang over the main target area, but no one hits the surrounding bases. It happens frequently with the defenders: Base is under attack so they roll jabos or buffs from elsewhere to hit troops and ords at the surrounding fields. However I seldom see the attackers target secondary objectives to draw defenders away from the primary objective, or deny them the resources to adequately support the defense.
