you can always trained yourself to create tanks for fh2.
If they are good enough, you could still donate them (or even join the team) and move FH2 nearer the early western front.
Think also that some french tank were used in normandy 1944.
The main problem with the early western front is its lack of "fashion" for a lot of players(only real ww2 players really want the early western war) because of the lack of AR, bazooka etc ...
So imo it will be done pieces by pieces. And one day, when there will be enough pieces, the team could make a big push to finish that front. (Manpower is one of the main reason for choosing a front imo)
