Good question Wulf.  I spent about 2 months playing offline before going online and the practice sure helped (though they didn't have drones back then).
I would imagine that the introduction of a better offline play would have two effects:-
1  Increased ACM within the MA.  I'm sure everyone would benefit to practice like the WB offline.  I sure do anyway.
2  Some people may not wish to go online, but I would imagine that would be very few.
So yeah, I would love to see a better offline mode, especially with vehicles, but I know HTC are busy so I can wait a bit more!   

Bring on the Navy!!
