I did add it to my wanted list some while ago.
The problem with these types of games,and one I came across with 'Holdfast : Nations At War' is that it requires a little discipline when assembling a group for 'volley fire'. Yes,some will march to the front lines and form up properly but when playing with randoms that can't be guaranteed.
Having said that,I don't know exactly what the game mechanics are for this game but I did watch a few Youtube videos and forming up and firing discipline did seem to play a part in the game play.
