Any second grader can plan a successful mission. The elements are incredibly simple. I have however, seen a couple intricate missions that relied heavily on timing, diversions, and multiple targets. Jokers jokers did one months ago on titanic tuesday that was very memorable. The vast majority of the missions I see though are giant hordes who swarm a base and then bicker on range about if the town is/isn't down yet and if the map room has/hasn't been strafed yet. It's pretty lame.
