Thanks for the feedback Animl & Randy, hopefully it will be a good addition to the rotation.
Randy on the short spawns, I currently have them set at 1.5 miles from the map rooms, with the incoming spawn points at 3.0 miles. I can increase the short spawns to 2.0 miles, the additional 1/2 mile might do it. I'll experiment a little and see if that does it. I agree that a T34/85 being able to beat an M3 to town, does not contribute to good game action or balance offensive/defensive conditions of a map.
