If you're an ED Tester, you've been doing a horrible job at it. The current state of MP stability may be why most players have stopped going online. But nothing beats PvP or coop. A human will give you a better fight, any day. The current AI cheats and has minimal limitations imposed by gravity, weight, thrust or realism.
So these scripted campaigns are a one trick pony. Good for 1 play, then done. Unless you enjoy winning by memorizing the AI moves on a mission you've played over and over.
