You are right of course. It reflects situation accurately for the "standard horde" since they are supposed to be people that have picked up arms out of need to defend themselves until they find a new home and settle.
Remnants of a defeated army i.e. seasoned warriors and "freedom fighters"? Not really…
DoM is the the next version. Sorry, your question is quite incomprehensible to me. Could you please reformulate?
EDIT:
Did you meant could they include The New Shadow as a provincial campaign in the DoM? I honestly don’t see the point since you can have both. Folder name will be changed, so DoM will not overwrite TNS.
