I ran though it just to see how long it would take with full HP enemies.

As a solo acrotecher (Bruce and Ethan) it took 1:23. Most of the time was spent with Gaozoran and the Vanda Orga. Other than those two creatures it was pretty straight forward. It seems like a big waste of time with the decreased Mission Rewards. The old MAG' at least was good for MP, but this version isn't even good for that.
