Not that silly and loads of fun.
I didn't know the DME existed for the first 3 months I had the game. Once I discovered it I was able to make some really great missions. Yep it beat the hell out of putting some armor units on the map and then flying the mission and noting which way to move each piece. Exiting the mission. Loading the mission and then adjusting the x and y values in the mission editor to move the pieces. Flying the mission. Looking at the pieces and noting their positions and any corrections that need to be made. Then exiting the mission. Then returning to the mission builder, and loading the mission editing the x and y coordinates again and again. Yep lots more fun with the ole DME.
