How about this. Instead of just being able to load up a goon with troops that only go after the map room, what about being able to drop demolition troops that go after town buildings. Drop ten of these demolition troops and you take down ten buildings. The only time element is how long it takes them to run to a building. If two troops are running to the same building and one gets there first then the second one automatically switches targets. So fly in 4 or 5 goons with demolition units and one to capture the town once everything is down. This wouldn't work on Vbases or ports since the ack would shoot all the troops before they could do anything.
Just something I thought of today, haven't really pondered the concept very much.
