Well I don't agree on this, I think it is quite weak. Very few options, only two simple mission goals ( destroy or survive ), no TOTs that any unit would care about ( you have to run the mission and write down actual times over waypoints by hand to coordinate units ! ) etc.
I think meangreen made a very good post. I would love to see mission planing like Tornado ( altough I never played the sim myselfe, I did hear only good about it ). But I have to agree with GGTharos, first we need a advanced mission editor, only then we have a good basis for a DC.
